Cave Calcite Aragonite Raw Mineral Specimen UV Reactive

Commonly known as "cave calcite" or "cave popcorn", although these are aragonite. Aragonite and calcite are chemically the same (calcium carbonate), however, they form crystals differently.This mineral forms within caves, mines and moist areas that are rich in limestone. Formations occur as stalactites and stalagmites. Cave calcite forms in a variety of colors ranging from clear, to milky white, and, as seen in this listing as a rusty oranges. These colors, in addition to their coral-like formations, make cave calcite great addition to any collection.
