Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO3). The Mohs scale of mineral hardness, based on scratch hardness comparison, defines value 3 as calcite. Other polymorphs of calcium carbonate are the minerals aragonite and vaterite. Aragonite will change to c

🐉Epic Dragon Scale Calcite💎✨ An absolutely glorious two toned, double terminated Dragon Scale Calcite from the Sweetwater Mine, Missouri. We made a custom base for this piece which was difficult because it needed to stand on many crystal points but we love how it turned out. This one has found a home but we have a few more!🐉🐉🐉 | Rocks for the Spirit

💎 Calcite – A calcium carbonate mineral with the formula CaCO₃, and one of the most common and widespread minerals on Earth. It crystallises in the trigonal system and is the primary component of limestone and marble, as well as a common gangue mineral in many ore deposits. Calcite occurs in a wide variety of habits including scalenohedral ("dogtooth"), rhombohedral, prismatic, fibrous, and massive forms. It ranges in colour from colourless and white to yellow, orange, pink, green, blue, brown,
