2.8" Calcite Crystal Cluster with Purple Fluorite - China

This is an intriguing, 2.8" wide, calcite crystal cluster that is part of a new find in Qinglong, China. The scalenohedral calcite crystals are encrusted in small, cubic, purple fluorite crystals. It is claimed that this fluorite is Yttrofluorite (fluorite containing an appreciable amount of the rare earth element yttrium), but we have not been able to independently verify this.
