3.8" Orange Cave Calcite (Aragonite) Formation - Peru

This is a beautiful formation of orange aragonite (aka cave calcite), collected from the Pachacayo Mine in Junín, Peru. When viewing the mineral under short and long wave UV, this specimen fluoresces a faint, white-yellow color. Following extended UV exposure, the aragonite displays phosphorescent properties that remain for a short time.

Comes with an acrylic display stand.

Cave calcite is not actually calcite but is formed from aragonite crystals. Calcite and aragonite are both carbonates with the same chemical formula (CaCO3), but different crystal structures and symmetries.

Cave calcite forms underground due to groundwater deposition. While it often forms stalactites and stalagmites it can also form unique, branching, tree-like structures or botryoidal formations.
