OPTICAL CALCITE (ICELAND SPAR)
Optical Calcite or 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, easily divisible into rhombs, and is remarkable for its double refraction. Historically, the phenomena of this crystal were studied at length by Christiaan Huygens and Isaac Newton. Sir George Stokes also studied the phenomenon.
Mines producing Iceland spar include many mines producing related calcite and aragonite as well as famously in Iceland and productively in the greater Sonoran desert region as in Chihuahua, Mexico and throughout New Mexico in the United States.

Also called Iceland Spar, Optical Calcite works to clear and activate all of the chakras, improving the flow of energy throughout the subtle bodies. Meditation with Optical Calcite can help to improve one's perception of the physical world and of the self, creating a shift in those who experience predominantly negative emotions. Use Optical Calcite to clear away negative energy, and to amplify positive energy, and specifically, to help remove fear-based emotions, bringing more optimism into one's experience.
Optical Calcite is helpful for those in need of clarity, and those who are learning about Law of Attraction and manifestation. Like Clear Quartz, Optical Calcite can amplify intent, and can be programmed for a specific purpose. Optical Calcite can help one to see past errors and ways to correct them for benefit in the future. By clearing away stagnant energy blockages, Optical Calcite can bring higher energies into the chakras, encouraging spiritual development.
You can read a newspaper through Optical Clear Calcite! Youre not seeing double when you look through them, though; when light passes through this transparent Calcite it bends two ways, making images appear double. These Calcite pieces naturally form parallelogram shapes, making them excellent pieces for energy grids.
In general, Calcite is a powerful energy amplifier and cleanser. The purifying energy of Calcite cleans out stored negative energy from a room, the body, etc. Use Calcite to clear out old energy patterns and to increase personal motivation and drive. Calcite is also a good choice for distance healing work, because it amplifies the energy being sent.
Calcite is also know as the stone of the mind. Calcite heightens mental discernment and analysis, increases memory and learning abilities. Calcite is THE stone for students and academics. Calcite is also useful during times of mental adjustments and disagreements. Calcite can show you a new way to look at a situation, easing you away from old, outdated thought patterns that may be in the way of new ideas.
Physically, Calcite has been associated with the bones and joints, and balances the amount of calcium in the body. Calcite can also help to improve the body's absorption of important vitamins and minerals.
