About calcite
Calcite is a calcium carbonate mineral that is extremely common in the Earth's crust. It occurs in a wide range of colors and forms, including transparent rhombohedral crystals with strong birefringence. With Mohs hardness 3 and perfect cleavage in three directions, it is very soft and fragile for jewelry use.
