Calcite is a rock-forming mineral with a chemical formula of CaCO3. It is widespread and found throughout the world in sedimentary, metamorphic, and igneous rocks. Some geologists consider it to be a "ubiquitous mineral" – one that is found everywhere. Calcite is classed as a carbonate and has a vitreous or glassy luster.

Standard Calcite is a rock-forming mineral that's found inside sedimentary, igneous, and metamorphic rock. Technically speaking, it's a carbonate rock. But, the inspiring colors make it stand out despite the relatively basic chemical composition. Calcite comes in a spectrum of colors, and orange is one of the most intense.

Physical Properties of Calcite. Pure calcite is transparent and colorless but also occurs in white, gray, yellow, orange, red, brown, black, or rarely, also blue. Calcite defines the hardness 3 on Moh's scale with specific gravity 2.71 g/cm 3. It has vitreous luster and perfect cleavage in three dimensions.

Optical calcite is a beautiful clear quartz that has been used for centuries in a variety of mediums and ways. It is transparent and made up primarily of calcium carbonate. It has a strong birefringence and double refraction, meaning it can split a beam of light into two and refract it in two different directions.
