Calcite is one of the most common minerals in the world and is primarily used in the pharmaceutical industry due to its high calcium content. It is believed to have particularly good healing effects on bones, leading to its German name "Beinbruchstein" (bone-breaking stone). A notable characteristic of calcite is its double refraction, which gave rise to its variety name, double spar. Because of this unique property, pure crystals are also used in the optical industry. While calcite is less suitable as a gemstone due to its low hardness, it is occasionally cut into cabochons or smooth stones. Due to its abundance, calcite occurs in various colors and forms. Origin: Helmand Province, Afghanistan.
