Chemical Composition: Calcium Carbonate, CaCO3
Occurrence: Calcite crystals occur in a variety of forms, including hexagonal , trigonal, often resulting as a rhombohedron. Our optical calcite specimens are natural shaped crystals (not cut), which exhibit double refraction (an object viewed through the crystal appears as a double image. Try this: by setting the calcite crystal on top of a page of text.) White calcite crystals often form attached to other crystals, such as amethyst, citrine, and fluorite. Various forms of calcite may be found throughout the U.S., Brazil, China, and Mexico.
