5.35" Cave Calcite (Aragonite) Formation - Fluorescent

This is a beautiful, fluorescent aragonite (cave calcite) formation from Morocco. When viewing the mineral under natural and artificial light, aside from the interesting white botryoidal formations, the mineral may seem slightly uninspiring. But when placed under shortwave/longwave UV light, this mineral fluoresces a white-green color and displays a phosphorescence that lingers for a short period of time following removal of the UV light.

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.
