    Calcite is a carbonate mineral that makes up a significant portion of the Earth's crust. It's a polymorph of calcium carbonate, and one of Earth's softer minerals (a 3 on the Mohs scale of mineral hardness). It exhibits a perfect rhombohedral cleavage. Calcite is commonly used as a construction material - limestone is composed primarily of calcite, and marble is formed when limestone is subjected to heat and pressure. The different color varieties of calcite are due to impurities in the mineral. 

    This set includes white blue calcite, red calcite, green calcite, orange calcite, and Septarian calcite.
