Optical Calcite

Optical calcite comes from various regions including Iceland, United States and China. Optical calcite is double-refractive and ice-water clear.  When light passes through the transparent calcite it bends two ways, making images appear double.

It has more uses than any other mineral and is found everywhere on earth. Even the earth's crust is made up of a significant amount of calcite. It can be used as construction material (limestone and marble), abrasive cleaning agent, agricultural soil treatment, pharmaceuticals and more.

Calcite is believed to be a powerful spiritual cleanser, as well as a protective stone against negative energy. Calcite has also been believed to be increase healing, learning and awareness.

Calcite is associated with the sacral chakra.
