Calcite is a kind of calcium carbonate mineral, which is the most common in natural calcium carbonate. Therefore, calcite is a widely distributed mineral. The crystal shapes of calcite are various, and their aggregates can be clusters of crystals. It can also be granular, massive, fibrous, stalactite-like, soil-like, etc. You can get many square pieces by knocking calcite, so it is called calcite. The color of calcite varies with the impurities contained in it, such as iron and manganese. Sometimes it is light yellow, light red, brown-black, etc., but generally it is white or colorless. Colorless and transparent calcite is also called Iceland stone.
