8.5" Cave Calcite (Aragonite) Formation - Fluorescent
This is a large and beautiful formation of fluorescent calcite with aragonite, 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 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.
