Calcite, which is a form of calcium carbonate, may be a commonly encountered specimen, but that doesn’t detract one jot from its natural beauty. Depending on the chemical constituency and what other elements or impurities appear as inclusions in a calcite specimen, it may take on many different colors, including but not limited to white, yellow, purple and green. Here we carry a variety of calcite specimens presented with hematite, amethyst, dioptase, fluorite, and other minerals.
