1 x Optical Icelandic Spar Calcite slab
You will receive the exact item in the images.
Iceland spar, formerly known as Iceland crystal, is a transparent variety of calcite, or crystallized calcium carbonate, originally brought from Iceland, and used in demonstrating the polarization of light. It occurs in large readily cleavable crystals, is easily divisible into rhombuses, and is remarkable for its birefringence. This means that the index of refraction of the crystal is different for light of different polarization. A ray of unpolarized light passing through the crystal divides into two rays of perpendicular polarization directed at different angles, called double refraction. So objects seen through the crystal appear doubled.Historically, the double-refraction property of this crystal was important to understanding the nature of light as a wave. This was studied at length by Christiaan Huygens and Isaac Newton. Sir George Stokes also studied the phenomenon. Its complete explanation in terms of light polarization was published by Augustin-Jean Fresnel in the 1820s.
Just like it's optical qualities, Icelandic Spar gives you clarity on your path in life. This crystal can also be used as a tool to develop your clairvoyance as well as the other sensory gifts. Use this stone at the third eye and the crown chakra to amplify your connection with the Divine. Optical calcite helps clear energetic blockages and assists in releasing the past.
