About Calcite
Calcite is one of the most abundant and collectible minerals, prized for its extraordinary variety of crystal forms, vibrant colors, and remarkable optical properties. This trigonal calcium carbonate mineral exhibits thousands of different crystal shapes, from simple scalenohedra to complex combinations. Calcite specimens showcase nearly every color imaginable—from colorless and white to blue, green, yellow, orange, pink, and black—making it essential for any diverse mineral collection.Calcite deposits occur worldwide in sedimentary rocks, marble, caves, ore deposits, and hydrothermal veins. Notable collecting localities include Mexico’s Colossal Cave region, Iceland, Brazil, Romania, and the United States. Distinct color varieties derive from trace elements: manganese produces pink rhodochrosite-like tones, iron creates yellow and orange hues, and cobalt produces blue specimens. Each locality produces characteristically different crystal habits and color combinations.Browse our extensive calcite collection featuring specimens from renowned worldwide deposits.
