This unusual spiky Calcite specimen comes to us all the way from the Tonglushan Mine, Hubei Province in China! This Calcite specimen features intricate points of various heights while displaying a color combination of ruddish red and brown. Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate. The Mohs scale of mineral hardness, based on scratch hardness comparison, defines value 3 as "calcite". How is calcite formed? Calcite can form by direct precipitation from waters rich in calcium. As concentrations increase or the amount of water decreases crystals of solid calcite crystals form. Calcite can also form in caves and where springs emerge on the surface. Calcite metaphysically is believed to amplify thought, improve memory, and promote development. Each piece is similar, though no item at Crystal Joys is exactly the same as every item is a unique stone that is non-fabricated. Slight variations in color, size and shape may exist.
