China is one of the top five countries in the world producing high-quality calcite (also France, the United States, Iceland, England), and more from the “karst” “endogenous hydrothermal deposit”. The formation process is: “gasification-hydrothermal fluid” containing ore, which causes changes in “physical and chemical” conditions due to temperature, pressure and interaction with surrounding rock when flowing in various rock fissures and holes. Aggregate precipitation into a deposit. The calcite crystals in the sputum are in the form of a complex three-sided triangular facet or rhombohedron; the aggregates are granular, stalactite, scalloped, and clustered; usually no fat, or milky white. It has two "variants": one is "ice stone", more than the cave, forming beautiful and huge crystals, colorless transparent or golden yellow, with significant "birefringence" phenomenon; second is "Aragonite" ", also known as the stone, it is a variant of "homogeneous two elephants" with calcite.
