More DetailsOptical Properties of Calcite. Calcite is a uniaxial hexagonal-rhombohedral mineral with moderate refractive index, but extreme birefringence. It is so birefringent that it appears to have both negative and positive relief, depending on orientation. Calcite has many forms, but it is always calcite. ...
More DetailsCalcite, the most common form of natural calcium carbonate (CaCO 3), a widely distributed mineral known for the beautiful development and great variety of its crystals. It is polymorphous (same chemical formula but different crystal structure) with the minerals aragonite and vaterite and with several forms that apparently exist only under rather extreme experimental conditions.
