8.8" Orange Selenite Crystal Cluster (Fluorescent) - Peru

This is a beautiful yellow selenite crystal aggregation that was collected from Peru. The crystals are highly fluorescent (yellow-green) under short wave UV and emit phosphorescent light that remains several seconds after the UV light is turned off. Comes with a gibson display stand.

These crystals only form in conditions where mineral rich water containing selenite forming minerals (calcium & sulfur), evaporates. Every crystal is unique, just like a snowflake.

Selenite is a variety of gypsum, a soft sulfate mineral that is composed of calcium sulfate dihydrate (CaSO4 · H2O). When chemically pure, gypsum is transparent and colorless, however, impurities give the gypsum a diverse range of colors and formations. Desert rose, selenite and satin spar are just a few of the varieties of gypsum known to have formed though hydrothermal processes.
