   Blue Calcite is a form of calcium carbonate that is typically pale blue to blue-green in color, with a vitreous to waxy luster. It is commonly found in sedimentary rocks, such as limestone and dolomite, and is formed by the accumulation of organic remains, as well as through the precipitation of calcium carbonate from water

   Calcite has a long and storied history in human civilization, having been used for everything from building materials to decorative objects to medicinal remedies. The ancient Greeks and Romans believed that calcite could help ward off evil spirits and enhance memory and mental clarity. In the Middle Ages, calcite was used to create stained glass windows in cathedrals and churches.
