Brown Aragonite Sphere | 99 mm, 3.9 in | 1.4 kg Apatite While it's commonly colorless orThe principal member of the Aragonite Group, aragonite is the second most common polymorph of natural calcium carbonate (the most common is calcite). It is significantly less widespread and abundant than calcite and is formed under a much narrower range of physiochemical conditions. It is metastable relative to calcite and often converts to calcite accompanying changes in the environment. It is nearly always a low temperature, near surface mineral.
