Calcite

Calcite is calcium carbonate and one of the most varied collector minerals, admired for its rhombohedral, scalenohedral, prismatic, and tabular crystals, bright vitreous luster, perfect rhombohedral cleavage, and frequent transparency. It occurs in many colors, including colorless, white, golden, orange, pink, green, blue, and gray, and may show dramatic twinning, phantoms, fluorescence, or included forms. Collectors value calcite for its crystal diversity, optical clarity, locality character, associations, and sculptural display quality. Fine specimens from England, China, Mexico, Romania, Spain, Brazil, Elmwood in Tennessee, and the American Southwest can range from delicate miniatures to commanding cabinet pieces.
