Iceland spar, a transparent form, has been used for optical and crystallography research for two centuries. Physical Properties of Calcite. Calcite effervesces vigorously with dilute hydrochloric (muriatic) acid, which easily distinguishes calcite from dolomite. Calcite is brittle, often flourescent, sometimes thermo luminescent.

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.
