Blue Mist Lemurian Quartz Crystals

blue_mist_web-1Every now and again I come across a new type of crystal that says WOW! It jumps up and down, waves and shouts and sings and throws a bucket of cold water on your face! Then lets you gently bathe and relax in its glorious crystal light… And these Blue Mist Lemurian Quartz Crystals from Columbia are one such type of crystal.
The Blue Mist Crystals were formed in the mountains of Columbia over 100 million years ago. During their lifetime there was a 20 million year crisis when they were internally fractured and broken by the earth’s tumultuous upheavals. And after each one of these catastrophes the crystals healed themselves internally giving rise to the appearance of the blue mist. The yellowish colours near the base are due to the presence of another mineral, limonite.
The super clarity of the crystal tip flows down the crystal into the self-healed blue mist in the middle of the crystal and grounds at the limonite at the base. Somewhere in between the Blue Mist Crystal’s energy dives into your solar plexus and grounds your creative ideas into reality.
I gave these Blue Mist Crystals to 10 students who each reported similar feelings to those which I had found with these amazing crystals.
As a crystal healer I believe that Columbian Blue Mist Lemurian Quartz Crystals have the following qualities:
They make you feel both like a young child and an old wise person at the same time.
They smell musky at the limonite bottom end whilst the clear point smells like fresh mountain air. Try smelling your crystals if you haven’t before! Each type of crystal smells differently and most people can sense the subtle fragrance.
The focus of the energy from the Blue Mist Quartz Crystal is in the solar plexus.blue_mist_web-16a
Instantly calming emotionally and physically - people report feeling instantly calm as soon as they hold the Blue Mist Crystal; very peaceful with tingling sensations through their hands, arms and sometimes right through the whole body.
“Everything settled and the pain melted away” (Student, St Albans) Blue Mist Crystals can help relieve pain. I’ve worked with these with some of my own clients and they help with pain which is emotionally rooted and aggravated by stress.
The students (all female) said there was a feeling that these crystals would be beneficial for increasing fertility, sex drive and balancing hormones.  
The Blue Mist Crystal tastes of clean water, like a natural mineral spring. It can give you a feeling of water running over stones. It is fresh and cleansing. Touch different areas of the crystal to the tip of your tongue and you’ll discover they taste different from one another. (Always wash and cleanse your crystal first.) And if you didn’t know crystals have a taste then try it yourself with a clean non-soluble crystal; a quartz crystal is perfect for this.
Meditate with a Blue Mist Crystal and in your meditative state you’ll find as you move up through the crystal the energy moves down through you. It is grounding and uplifting at the same time; so it’s an excellent crystal for anyone working on any creative project, a new relationship, new business venture or anything else you want to manifest into reality. Some of the Blue Mist Crystals are also manifestation crystals and would be perfect for this sort of work. A manifestation crystal is any crystal (usually quartz) with another crystal growing inside (which is often also quartz). They are specialists in bringing your dreams, goals and desires into reality in your life; often very powerful tools for major life changes.

Crystal Healing - A Testimonial...

This is the personal story of one of my clients and students Kerry Gavin. She wants to share it hoping it will help others and she's posted it on Facebook for all to see who know her.

I'd like to share with you my story about Crystal Healing has been helping me. Most therapists know that unless we look after ourselves properly we can't help others, but sometimes I think we're so intent to help others we do forget about ourselves. I will try and keep this short... so as not to bore you, but I really hope by sharing this it will help some of you.

For nearly 2 years now I have been suffering from acid reflux. If any of you have had it it's blimmin awful. The biggest part for me was severe chest pains, sometimes so bad I could have sworn I had a heart attack. After nearly a year of trying all different meds, but still in so much pain I went to see a Kinesiologist. Amazing lady she was and I'd recommend her to anyone. After numerous testing's she found I had many food intolerances and I suffered with Candida which was passed down from birth. I had to change some of the foods I ate, take some medication for two months and use some cream and all would be cured. Well after a month I felt amazing so decided I didn't need anymore of the med... stupid I know, but I do know best...well not in this case, because the pain came back with a vengeance. So after sometime of suffering again I decided to restart the meds she'd prescribed, this time completing the full 2 months. Amazing I felt at the end of it, but sadly, gradually after a short period I had the chest pains again a real ache between my breastbone and over my right side. Although I know heart attack pain is generally on the left side there were times at night where the pain was so bad I feared I wouldn't wake up.

So what next, well Philip Permutt the Crystal Healer came next. I have been seeing him for the past few weeks and it's now safe to say I am cured! I always felt that there was more to this and could it have been an emotional issue I was carrying around. I thought I was fine, I knew there had been things in my life which had caused much upset and trauma, but thought I had dealt with them. Well clearly not because I was living in pain everyday. I kept going, because I had to, everyday putting on a brave face as most of us do because we have to. But actually we don't have to and sometimes we just need to face the fact that we all need a little help at times. Crystal Healing, I do this, but could I sort this problem for myself? No because I was too close and in this instance I needed someone to help me. Well he has helped me so much and I can't believe that I am now completely pain free. When I asked him why and how has this happened to me now, he said more than likely because I am ready for it, I am ready to let go of some of the things that no longer serve me, all the heartache I have carried around with me for years. It's still there, but it's not stored inside me now causing me harm. It is all part of my life experience and although I can't ever forget these things I am not letting them affect me in this way anymore and CRYSTALS yes those lovely gorgeous coloured stones and the healing from Phillip has helped me release all this. And now I really honestly do feel so much better and it's so nice to have a day where I'm not in constant pain.

I'm sorry to have waffled on if any of you have got this far. One day this will all go in my book ;-) but I just wanted to share with you my experience and let you know that's it's ok to admit you need help. Why suffer alone. Please do feel free to share this with anyone who you think may benefit from it. I do offer crystal healing myself (follow this link for more info on Kerry's treatments).
Lots of love and light to you xxx

Blue Barite Crystal

Blue BariteBaryte_01a_mini
These amazing blue barite crystals are like "angel wings". Although barite is found worldwide and is not unusual, the blue crystals are very rare and are only found in a few places in the world. Ours come from Morocco.

Barite Mineral Properties
Baryte_09miniBarite forms tabular crystals in many colours including blue, white, grey, yellow, brown and can also be colourless. It can also form layered "plates" and fibrous masses and rarely a desert rose barite crystal formation. Common alternate names include barytes, baryte and barytine.
Astrologically barite is associated with the star sign Aquarius. It resonates with the throat chakra.

Healing qualities of barite
Barite gives you a "go for it!" attitude where everything becomes possible. It promotes friendship, harmony and love and can give you a deep insight into relationships. Blue Barite crystals also help catharsis, the process of releasing, and thereby providing relief from, strong or repressed emotions. It can help you overcome shyness. It is good for eyesight and helping you to “see” answers and promotes alternative ways of looking at a problem or issue. Barite is an excellent crystal for alternative and complimentary therapists. Barite is also a great detox crystal and is helpful when recovering from addiction. Blue Barite works exceptionally well on the throat chakra and promotes communication of ideas and thoughts, gives a spiritual connection or direction and helps you find your spiritual path though life.

Shungite - Where science and crystal magic meet

Shungite
shungite_01Every now and again there comes along a different crystal which is something special. Shungite is one such very special and amazing crystal! It is an ancient stone, around 2 billion years old! That’s old. Seriously old when you think that some of the oldest quartz deposits in Brazil are “only” around 200-500 million years old. It’s also one of the crossover crystals – crossing over from traditional shamanic crystal healing into modern medicine. Shungite has been used in medicine since 1700s for its antibacterial and water purifying qualities. (See I.F.Volfson et al Medical Geology: A Regional Synthesis retrieved 2012). It has an unusually high and unique carbon content.

Being 2 billion years old shungite predates life on Earth. It was here before any of us! It has a different feel and knowledge to share with us and amazing healing properties.

As well as purifying water shungite purifies all states of the body, mind and spirit. Shungite is good for psychic protection defending against negative energies from other people as well as those that might be in our environment such as electromagnetic radiation emitted from computers, microwaves, TVs, mobile phones (cell phones) etc.   It brings balance on all levels and promotes recovery from disease as well as tissue regeneration and growth.

Shungite is known as ‘The Stone of Life’ due to its amazing healing and antibacterial properties. It is a natural antioxidant that can increase immunity to many illnesses and counters the development of allergies.  As shungite naturally purifies water, drinking shungite enhanced water elixir can help to remove some health threatening molecules and free radicals from your system. It acts as a catalyst for the decomposition of organic matter and as it carries many microelements and biologically active substances it may be medically beneficial. It intensifies somatic biological processes but more research is needed on this. Shungite has been shown to interact with electromagnetic fields neutralizing their negative impact. It is good for dispelling over-sensitivity to electro-magnetic fields (EMF) and geopathic stress.

Shungite absorbs elements and chemicals from its natural surroundings and this is one of several scientifically important properties of shungite. Others include: medically its anti-inflammatory and antihistamine effects, in astrophysics it shows the ability to shield radio waves, in quantum physics it acts as an electro conductor and in the field of biology it has been shown to have the ability to absorb oxygen and actively interact with it. Modern science has only experimented with this since the 1990s and serious research into shungite’s practical applications started only a few years ago. Scientists are currently working on many projects using fullerenes derived from shungite including: in makeup to stop UV damage to the skin, as part of a new generation of solar panel devices and as part future of techniques to help allergic conditions, including asthma. This is really just the start, there is much, much more to come.

Shungite knowledge – the wisdom of this stone is fascinating and this bit is going to blow your mind! Ever heard of fullerenes? Well fullerene is an odd form of carbon based mineral found in just a few places in nature including hidden in soot, formed in the atmosphere in lightning bolts, meteorites, the depths of outer space… oh yes, and of course shungite. One scientific theory suggests that these complex carbon molecules are the precursors of life on earth and are the very seeds from space that over the last 2 billion years have produced you and me walking on the planet’s surface and reading and writing this. Shungite is the only natural consistent source of fullerenes.

Research into shungite has also shown that direct contact with the stone can provide relief from pain and help to alleviate a number of diseases; especially of the musculoskeletal system, skin conditions and speeds healing of the skin, cuts and bruises.

Shungite resonates with all the chakras bringing each into balance. At the base chakra it is grounding, helping you to feel the Earth beneath your feet. Placed on the sacral chakra it can help you find new energy and direction for any project. Laying shungite on the solar plexus expands your creativity. With the heart centre a loving connection is born, helping you to connect with and see the beauty in everything around you. Placed on the throat it can help you to say the things that you need to say to others in a kind way. Placed on the brow it can help you see into the future and promotes dreams and premonition. Shungite opens the crown chakra enhancing meditation and mystical experience.

Shungite is an ancient rock and as such helps you connect to your spirit guides. It promotes magical experiences and leads you towards discovering the mysteries of life. It can help dreams and premonition and is a wonderful stone for psychic readers, tarot card and angel card readings.

I feel it brings emotional balance, a calm stillness to emotional storms.

Carry shungite with you 24/7 to keep you protected from unhelpful energies. Put a piece of shungite in bottle of mineral water overnight and drink it the following day for a general tonic health boost and physical detox.

Turquoise

Turquoise
Turquoise is a secondary cooper appearing as a blue or green rock. The colour being due to copper and iron. The more iron the greener the stone, the more copper the bluer. It forms as nodules, veins, crusts, stalactites and rarely, small crystals. The name comes from the French "Pierre Turquoise" meaning Stone of Turkey.

Turquoise is the birthstone of December and has astrological affinities with Aquarius, Sagittarius, Cancer, Scorpio and Pisces. It is a stone held sacred by Medicine People all over the world and is often associated with the night.

Physically Turquoise acts as a general tonic for the body. Boosting the immune system and strengthening all tissues. It aids cellular and tissue regeneration by promoting the  absorption of nutrients. It is a wonderful stone to work with before or after any surgery, illness or when recovering from disease. It is also said to prevent physical accidents and prepare the body for traumatic events, such as surgery. Turquoise gives you a boost when you're feeling run down. It is also helpful in treating conditions of the spine.

Because of its effect on the immune system turquoise is protective and is said to prevent accidents and affects from environmental pollutants causing allergic reactions. Its has also been used to protect against the 'evil eye' and is a traditional form of protection for travellers. Some say it will protect you from radiation emitted from microwaves, mobile phones, computers and television screens.

Turquoise helps many chest complaints including asthma, bronchitis, breathing problems, shortness of breath, poor respiration, flu symptoms and fevers.

It is also beneficial in the treatment of arthritis and rheumatism. It is a traditional remedy for hip problems and is high in phosphoric acid, which is the homeopathic remedy for such conditions. It will also help alleviate wind pains and promote weight gain when you need it.

Perhaps Turquoise comes into its own in the area of the Throat Chakra. It is wonderful for public speaking and creative expression. It gives you the courage to communicate your own ideas and to connect to the spirit world.

Turquoise is a stone of friendship and emotional balance. By helping you express yourself it releases emotions and trauma often buried for many years. It will give you the strength to cope with these releases on physical, emotional, mental and spiritual levels. Turquoise promotes trust and kindness, dispels negativity and thereby reduces stress. It is a grounding stone, helping you to bring spiritual experiences into your everyday life. It helps to balance Yin and Yang energies within you allowing you to see the beauty in everything. This ties in with Turquoise traditionally being used as a love charm, promoting spontaneity in romance and love. It is also linked to friendship and loyalty and it is thought to change colour if your lover is unfaithful or the wearer is close to death. (Don't panic! If your Turquoise pales, leave it in the bathroom or a damp area for a few days and the colour will return. If it doesn't... then panic!).

It is said that Turquoise increases your innate healing powers and can be a steadying influence when placed in the centre of a room or group of people.

Historically Turquoise is linked with horses, bringing surefootedness. The Romans believed it protected their horses from accidents and fatigue and jockeys, hunters and horsemen often carry it to this day.

To Native American Indians Turquoise is perhaps the most sacred of stones. It represents the Blue Road, that is your spiritual path through life. It also represents Father Sky, Breath of Life and Spirit. It protects the wearer from the night and malevolent spirits. Turquoise connects Father Sky to Mother Earth and is used extensively in Rainmaking ceremonies and whilst Journeying.

The Aztecs made sacred Masks of Tezcatlipoca (a powerful God) from pieces of Turquoise shaped around a human skull. Tibetan Shamans used it in all ceremonies for protection. It is often set in the forehead of statues of Buddha to symbolise knowledge of things to come.

Turquoise was one of the most prized stones in the ancient world. It is known that Turquoise was mined in the Sinai Desert as far back as 3900BC and made into beads, ornaments, jewellery and scarabs. In fact the use of Turquoise goes back to the earliest jewellery ever found.
The story of The Turquoise Arrow comes from Tibet. It is fired from a Golden Bow. The Turquoise Arrow representing the Heavens and Golden Bow the Solar Rays of the Sun. In Tibet it is known as the 'Gem of the Gods'.

Traditionally Turquoise helps the spiritual person resist the temptations of the material world.

There is a magical ceremony for inducing wealth and financial gain. It must be performed in the hour of Jupiter. Holding a piece of Turquoise in the right hand, speak your desire into the stone whilst holding a steady gaze on it. Like all magic repetition increases the efficiency.

Tucson Gem & Mineral Show 2014 - Highlights

 We are back from an amazing trip to the Tucson Gem & Mineral Show and are shipping our crystalicious stock which should be here next week (w/c 24/2).  

It's the biggest crystal, rock, gem and mineral show in the world. It's out of this world... well some of the meteorites, moon rock and tektites are :-) 

 At the unit right now are tourmaline crystals, moldavite, Libyan glass (a yellow tektite with a similar feel to moldavite) zincite and a few moldavite pendants. 

 On our first day we found magical mini quartz crystals perfect for quartz stars, pretty pink Manganoan Calcite specimens (should have said bloody amazing!!! They are the best we've seen!!), stunning silver crystal specimens - which are also the very very best we've ever had! And a newly found crystal blue barite - much much more to follow about this one! 

The second day started aquiring Fire Opals from a Mexican gentleman who'd probably been pouring tequila on his cornflakes! Que Sera stone, hundreds of hunky Herkimers, Lemurian quartz crystals and pink Lemurian quartz crystals, Super 7 pendulums - and YES you did just read that correctly - Super 7!!!!  Then had a lovely hour with our old friend Melody and swapped stories and books. 

 

After lunch we had much Brazilian dealing picking up rutilated smokey quartz, excellent chevron amethyst crystal points perfect for pain prevention, one very special crystal skull carving, tourmaline crystals including watermelon, bi-colours, pink, elbaite and one piece of rare achroite  A large batch of natural citrine crystals, wondrous polished natural citrine points, large quartz double terminated crystals - perfect for talking crystals  and a batch of natural dark smokey quartz including one massive crystal point - a day of Wows! 

 Early start again on day 3 aiming at spending the morning with our old friend David Geiger but we were slightly distracted as happens often in Tucson… So we start selecting some very interesting crystal balls in various materials including pyrite, rhodochrosite, manganoan calcite, lepidolite, nephrite jade, gabbro (more of this later :-)), chrysocolla and epidote. So on to visit our friend David when funnily enough something caught our attention… Chinese jade carvings including a wondrous white jade Quan Yin. Right on to David… Gabbro… what exactly is gabbro? I think I’ll write a blog on this one when I have time because the energy was absolutely amazing… so we bought some more! Wands and palm stones … So David, right? Yea! We finally arrive at his show room 2 1/2 hours after we get to the show and Lyn goes woosey… just like she did when we first met the original Russian Lemurian quartz crystals over a decade ago… wonder what she’s got cooking this time… stay tuned...

 

We found eudialyte which is becoming harder to find but works so wonderfully with morganite to clear things out and heal the heart. An interesting ad hoc meeting with a US publisher and somewhere along the way we also picked up amethyst, citrine, quartz, rutilated quartz and tourmalinated quartz freeform crystals. Oh yes and kyanite sticks, watermelon tourmaline slices and I almost forgot the moldavite pendants  We ended the afternoon meeting up with Ashley Leavy & Diane Doughman from Mimosa Books. Right we’re off to bed and we’ll be up bright and early again tomorrow bringing you the best from Tucson!

 

Sunshine greets our 4th day in Tucson as we wander to one of our regular Chinese dealers and as is the way here the deal is ongoing and might be another day or 2 to complete but I can tell you that it includes stunning lapis lazuli points and bowls and a selection of crystal bowls, some unusual tumble stones, 

palm stones (that we have an idea for) and several other crystal treats  Then we found some great moldavite and zincite. Had most of the afternoon off and wandered in to look at a fossil show… where we bought… erm… No! Not fossils but more crystals Small specimen pyrite crystals, malachite, pyrite suns, amazing azurite specimens and spacey meteorites that are out of this world

 Lots more to see and do… see you tomorrow night x

The Tucson Gem & Mineral Show always holds surprises. Sometimes it’s the people you meet, sometimes the crystals. On day 5 we had 2 amazing crystal finds… first was early in the day, in fact one of our first buys, a perfect miniature dioptase cave  and the second was right at the end of the day and our last buy; a crystalicious collection of super polished crystal points including amethyst and smokey quartz elestials, clear, rutilated and tourmalinated quartz, citrine and golden healer quartz. It’s a one off crystal collection that we’re sure you’ll fall in love with. 

Other crystal finds include black tourmaline crystals, pink opal, really bright orange calcite wands, lava rock palm stones, very clear quartz standing crystals, and blue apatite. 

Magical malachite and great Native American horn rattles signed by the artist, sage smudge sticks, abalone shells, key chains/key rings, neck pouches and 1 very special smudging fan. I know several people who will be waiting for these to arrive! 

Day 6… a day of moving boxes! Arranged the shipping and started loading our pallet. Collected our crystals from our Mexican friends including blue and orange calcite, obsidian arrowheads, some very special natural chalcopyrite,hand size specimen desert roses, large calcite display pieces and acquired some lovely scolercite from the stand next door. We finally found some small selenite spheres – it seems that no one brought them to the show! We found some amazing tumbled natural citrine , sunstone and “African gold” that feels amazing! I was just drawn to it as it screamed at me across the tent. 
Then rounded the day with one of our specialities… aqua aura We are bringing back clusters, points, drusy, stars, mini crystals for quartz star healing technique, DT crystals, angel aura, titanium quartz and one very, very special large aqua aura cluster fantastic quality. 
We also met Judy Levy from Maui who stocks and loves my books and invited us there next year to teach my crystal healing courses - what a wonderful world Tucson can be...  

 Our find of the show!!!! A beautiful Buddha carved from a single large tanzanite crystal! Wow!! Seriously crystalicious :-)

 

The next day was a day off from crystal shopping and we absorbed ourselves in the desert and American Indian Culture...

Day 8… Back to work! And what a great day! Went back to buy ALL the small pyrite crystal specimens that we could because they’re really amazing both energetically and as a collectors mineral, and because they’re small they are very inexpensive  We also scored a bountiful batch of biotite mica. Brilliant black tourmaline crystal pendants set in silver. A small stunning collection of Buddhas and Ganeshes and a shell (?) and an eagle, which were all carved by hand by very spiritual people from India and all have a beautiful soft energy. Hand polished kyanite palm stones. And one of the finds of the day Libyan glass tektites from… er… Libya. One more day of crystal shopping to go… 

 

 

 Early start on our last buying day as we go to several shows to do the final haggling and pick up some of the things we've seen but haven't bought yet then planning to meet up with American author Hibiscus Moon for a scenic coffee at the end of the day.

New stock will be here next week. Contact us to arrange an appointment to see our amazing, beautiful crystalicious crystals when they arrive!

Tucson Gem & Mineral Show 2014

The Tucson Gem & Mineral Show is the biggest crystal, gem, mineral and fossil show in the world.  It is a massive event that almost takes over the city. To give you an idea of the scale - in the UK a mineral show may have 30 - 200 exhibitors.  In Tucson there are around 40 shows (yes, forty!). There are dozens running at the same time. Some run for over 3 weeks whilst others are only on for a few days. They are in hotels, resorts, exhibition halls, tents both small and large... very large... very, very large with some covering several acres!  The smaller ones have around a couple of hundred exhibitors and the 5 largest have over 1,000 exhibitors in each!  Someone once worked it out that if you spent 5 minutes at each exhibitor, didn't sleep, eat or stop to buy anything, then it would take about 5 weeks to go round and see everything.  Most of the shows are only on over 2 weeks!!

So we travel 5,281 miles... each way... walk around in the Arizona winter sunshine, whilst it's mostly snowing and raining and windy and wintry at home, looking and the most beautiful and unusual things on this planet. Work, work, work... Life can be so tough :-)
But we also remember that we are actually working and we'll probably spend 80% of our anual budget for stock in 10 days!

So please feel free to let us know anything you'd like in the way of crystals, fossils and Native American goods and we'll try and find whatever you want - see below...

Tucson Gem & Mineral Show 2014
Lyn and I will be in Tucson, USA for the Gem Show between 31/1 and 10/2. We're happy to take orders and requests for any crystal on the planet (and a few that have come from space too!) but there is so much to see that our time there is limited so this is how this works... You can 
1) Request - Which means we'll pick some up if we see it along the way. Just ask by email with your phone and email details and we'll let you know when we get back.
2) Order - this is a firm order in which you describe the items you'd like and we'll buy it for you if we find something that matches your description. We'll give you an estimate of price before we go and you'll need to give us your card details to charge when and if we find it.
3) Special Order - For special or larger items - this is also a firm order but with this we will specially source the crystals for you at the shows. You will need to give your card and contact details as above and specify a maximum budget. 
All prices quoted for Tucson orders will be as delivered to our Unit in St Albans. If you cannot collect, then additional delivery charge may apply.  Click here to Contact Us

Iceland Spar: The Rock That Discovered Optics

Iceland Spar: The Rock That Discovered Optics

A Guest Blog Post by 

Every year, I can’t think of anything I want for Christmas.  So this year, I was pretty excited to come home and tell my wife, “I know exactly what I want for Christmas. A nice big piece of Iceland spar.” I even sent her a link to make it easy. (It’s certainly a comment on our times that I sent a text link across the room to my wife.)

 

It’s not motion blur, it’s Iceland spar! 

 

“Really? You want a  $100 rock for Christmas?” she asked. I considered mentioning that the price of the rock I want is a tiny fraction of the price of the rock she wants, but thought better of it because she was giving me that look she gives me sometimes. You know, the look that says she knows that at some time there was some reason she chose me, but at this moment she can’t remember when that time was nor that reason.

Instead, I started to explain how Iceland spar is probably the coolest, most important substance ever. How the Vikings probably used it to find America. How Iceland spar was a key to discovering what light actually was. That every great name in optics from Huygens, to Newton, to Fresnel, and even Edwin Land (of Polaroid fame) used Iceland spar. How a shortage of Iceland spar in the late 1800s was considered an emergency by almost every industrial nation. That Iceland spar helped win World War II and can make things invisible.

Of course, before I could tell her even half of that stuff, she rolled her eyes and wrinkled her nose the way she does when the dogs or I bring something into the house that she feels would best be left outside to further decompose. She did look at the link I sent, though, because she asked, “Why does something called Iceland spar come from Mexico?”

I’m pretty sure she wasn’t particularly interested in the answer, because she immediately started talking to herself. Something about whether there were mature, grown-up males anywhere on the planet. My response, that they raised unicorns near Atlantis, apparently has created enough ‘alone time’ for me to write this post and tell you all the cool stuff I didn’t get to tell her. And to order a piece of Iceland spar, because I’m fairly certain it won’t be under the tree.

So, What is Iceland spar?

Iceland spar is a crystal of calcite (calcium carbonate). Calcite is a fairly common mineral and comes in a spectacular range of colors caused by the impurities it contains.

Iceland spar is rather unique among the calcites. It contains no impurities, so it’s nearly colorless and transparent to both visible and ultraviolet light. For centuries, the only source of this pure calcite was located near Reydarfjördur fjord in eastern Iceland, hence most of the world called it Iceland spar (spar means a crystal with smooth surfaces). The Icelanders just called it silfurberg, meaning silver rock.

A crystal of Iceland spar has two very interesting properties. First, it is a natural polarizing filter. Second, because of its natural polarization, Iceland spar is birefringent, meaning light rays entering the crystal become polarized, split, and take two paths to exit the crystal – creating a double image of an object seen through the crystal.

There is good evidence that the Vikings used the polarizing effect of Iceland spar to navigate the North Atlantic. The constant fog and mist in the North Atlantic often make navigation by stars or sun impossible. The Vikings called Iceland spar a ‘sunstone’ because the polarizing effect can be used to find the direction of the sun even in dense fog and overcast conditions. It can even find the direction of the sun when the sun is actually below the horizon, as happens when you’re sailing above the Arctic circle.

The second interesting feature of Iceland spar is birefringence, meaning it refracts light into two separate images, is more noticeable. The double image may just seem mildly interesting to you and me. But it turned the scientific world (at least the optical part of it) upside down back in the 1600s.

Iceland Spar and the Theories of Light

Rasmus Bartholin of Copenhagen made the first written reports about Icelandic spar in 1669. At the time, Snell’s law of refraction were well known. Snell’s law said a regular crystal would bend light rays a given amount and there was a nice formula to calculate that amount. But Bartholin’s report showed that Iceland spar bent light two different amounts, creating two different images. This seemed to break Snell’s law.

Within a few years, Bartholin’s findings had been discussed throughout Europe and scientists (they would have called themselves natural philosophers back then) were begging for samples of Iceland spar. (They had to beg from people in Denmark, like Bartholin, because Iceland was part of the Danish Kingdom.) Among those begging were Christiaan Huygens and Isaac Newton.

Christiaan Huygens, in addition to originating Troy Polamalu’s hair cut, was an amazingly brilliant and productive man. He discovered the formula for centripetal force, invented the pendulum clock and the pocket watch, and discovered Saturn’s rings and largest moon (Titan) as well as the Orion nebula.

Huygens spent over a year experimenting with Iceland spar after Bartholin sent him some samples. He discovered that putting a second piece of Icelandic spar over the first piece didn’t make 4 images out of the two seen through the first piece of spar. In fact, by rotating a second piece over the first, he could make either of the original two images disappear.

The reason, we now know, is that Iceland spar is a natural polarizer. It splits the incoming light into two polarized beams, making two images. By using a second piece of Iceland spar he could block either of the polarized images originating from the first piece. I don’t have a second piece of Iceland spar handy, but I can do the same thing Huygens did by putting a polarizing filter on my lens. Depending upon which way I rotate the polarizer I can eliminate either one of the refracted images.

Huygens decided the two refractions were best explained by considering light a spherical wavefront; that the crystal separated the waves in two slightly different directions because of different velocities of the waves. He developed formulae mathematically describing the geometry of such waves, which originated much of modern geometric optics. Unfortunately, his wave theory of light was not widely accepted at the time, partly because his longitudinal waves did not really explain birefringence very well. His formulae for geometric optics were accepted, though, because they generally worked.

Isaac Newton had already determined that white light is made up of various colors and that the different colors refracted different amounts (what we now think of as chromatic aberration). He had decided that light was not waves, but rather ‘corpuscles’ or particles (which is also correct). He proved that Huygens wave theory could not really explain the double refraction of Icelandic spar. Instead, he claimed, birefringence occurred because light particles had two sides, and the crystal separated those sides. Newton couldn’t prove this, of course, but his reputation being what it was people generally accepted it for the next 100 years or so.

 

Isaac Newton

 

Iceland spar, then, contributed to the original development of both the wave and particle theories of light as the great optical scientists of the day tried to explain birefringence. Oddly enough, neither theory explained birefringence very well. At the time, both theories were partially correct and partially incomplete. They would remain that way for over a century until Thomas Young came along.

Young definitely proved the wavelike nature of light in 1801 in a series of experiments that (unfortunately) had nothing to do with Iceland spar. Soon after that, though, a French scientist, Etienne Louis Malus, noticed the polarizing effects of Iceland spar when he rotated it and looked at sunlight from various angles. He experimented with it and eventually developed Malus’ Law, which predicts the strength of a beam of polarized light when passing through another polarizer.

A decade later, both Young and Augustin-Jean Fresnel (of Fresnel lens fame) finally explained the polarization of Icelandic spar. When they thought of light waves as transverse (like ripples in a pond) not longitudinal (like a slinky), then polarization of the waves was possible, explaining the birefringence of Iceland spar. It was nearly 150 years after Huygens that Young and Fresnel finally developed a wave theory of light that explained polarization and birefringence.

Using Polarized Light

Once there was a good understanding of how Iceland spar polarized light, it wasn’t long before people put this new knowledge to practical use. With simple pieces of Iceland spar, scientists of the day discovered that the atmosphere polarized sunlight, that light from a comet’s tail was polarized, moonlight was partially polarized, and certain chemicals in solution were also polarized.

The Nicol prism was invented in 1828 by, not surprisingly, William Nicol. It consisted of two wedges of Icelandic spar joined together with a layer of Canadian balsam. When light is shined in one end the spar split the beams. Because of the two angles of refraction, one beam exits the end of the prism as polarized light. The other was refracted outside the prism and absorbed.

The Wollaston prism was aligned somewhat differently and emitted two beams of polarized light. Dozens of other types of polarizing prisms were developed over the next few years.

Scientists now had a source of polarized light to play with, and play with it they did. Photometers and spectrophotometers (instruments that measured light intensity and character) were developed. They were used both in pure scientific research and in the chemical industry. Polarimeters (instruments that measures the change of polarized light passing through solutions) detected the presence of, and measured the concentrations of, specific chemicals in solutions.

Chemical synthesis, extractions, and purity analysis exploded in the mid-1800s, largely because of these instruments. The sugar industry was rife with fraud before the development of polarimeters, but once they became available accurate measurements of sugar concentration could be made. Chemists could accurately assay concentrations for the first time, allowing them to purify numerous substances. Medicines changed from ground herbs of unknown concentration to purified preparations with known potency.

Polarized microscopes were used in biology and medicine, but also in geology to assess the authenticity of gems and crystals. For photographers and astronomers, crossed polarizers were used to assess optical glass and lenses. Flaws and defects in the glass which were invisible to visual inspection showed very clearly when examined by polarizers.

There were even early attempts to use Iceland spar to create 3-D imaging. In 1894, a British physicist named John Anderton patented a system that would project paired images through magic lanterns each equipped with Nicol prism polarizers in different orientations. A viewer with opposite oriented prisms would reproduce a 3-dimensional image. While the system would work in theory, it was probably too bulky and expensive to ever gain widespread use. (Edwin Land created a similar system in the 1930s with his polarized film.)

Every one of these scientific instruments used prisms made of Iceland spar to create polarized light. Iceland spar was no longer a scientific curiosity; it was a major industrial component used in thousands of measuring devices. With only one source of the crystals, it wasn’t surprising that significant shortages of Iceland spar occurred. The situation became so severe that European instrument makers got the governments of Germany and France to request increased mining in Iceland, but the mine there was nearly exhausted.

New sources were found first in South Africa and later in Mexico, the U. S., and South America. Even with these new sources, the supply was always limited. Worldwide mining produced a few tons of optical grade Iceland spar, at most, each year. For example, the mine at Taos County, New Mexico produced 850 pounds (not tons, pounds) of Iceland spar in 1939.

Iceland spar Goes Modern

Edwin Land’s invention of polarizing sheets and films in 1928 helped alleviate the Iceland spar shortage, although polarizing film was only useful in certain applications. Some other polarizing crystals, both natural and artificial, were also developed. But Iceland spar continued to be used in a variety of optical instruments and remained in great demand throughout the 20th century.

By an interesting coincidence, Edwin Land created some of this demand. When the United States entered World War II, one of its first needs was a small, accurate gun sight for its warplanes and anti-aircraft guns.  Aerial gun sights at the time were large bulky affairs with prisms and lenses. Land invented the optical ring sight, which consisted of two sheets of polarizing film and two optical wave plates sandwiching a crystal of Iceland spar. Iceland spar was considered a strategic resource by the U. S. government, which had classified studies done assessing the Iceland spar mines of South and Central American nations.

Optical calcite polarizers are used today as polarizers and beam-splitters in the the laser and fiberoptics industries. You can still find devices that contain Nicol and Wollaston prisms today, but the most common current use of calcite crystals is in Glan-type prisms. These can withstand very high luminance and are used to polarize laser light. Quartz and synthetic materials can be used in many, but not all of these applications, and synthetic calcite remains expensive and difficult to produce. Most of the optical calcite crystals used today are mined just like they were in the old days, which is why Iceland spar crystals remain rather pricey.

Perhaps the most interesting modern research using optical calcite is to actually make things invisible. Researchers have found that using a pair of shaped calcite crystals in certain media, they can effectively make small objects disappear in visible light. Light from behind the object bends right around it while passing through the two crystals. Viewed from the front it’s as if the object isn’t there. If you haven’t seen it, there’s a video of it as demonstrated at the 2013 Technology, Education and Design Conference HERE. It’s pretty amazing.

So There You Have It

Obviously I’ve managed to get one piece of Iceland spar. But I wouldn’t mind a second, so it’s still on my Christmas list. Maybe I could do some fun tricks with disappearing lines and such. Until then we’ve already put the original piece to good use topping the Lensrental’s Tech Room Christmas Tree.

 

 

And if there’s an optical geek on your Christmas list – well, now you’ve got a great idea for an original gift. You can get them a nice piece of Iceland spar. And just think how much fun it will be when they ask what it is and, armed with this post, you can smugly tell them geeky stuff they didn’t know.
