4.3" Cave Calcite Stalactite with Fluorescent Calcite - Wenshan Mine
This is an interesting cave calcite stalactite formation that's entirely encrusted in radiating, yellow calcite crystals. It is part of a new find at the Wenshan zinc mines in the Yunnan Province of China. The base of the specimen has been cut flat for aesthetic presentation.
Under short-wave ultraviolet light, the calcite crystals exhibit a stunning white fluorescence.

Cave calcite is not actually calcite but a formation of 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 on cave ceilings and floors, it can also form as unique, branching, tree-like structures. These beautiful formations are sometimes known as ‘floss ferri’ (flowers of iron) and frostwork.
