This vivid, sparkly yellow specimen features an incredibly rich coating of the very rare species jouravskite, in a carpet of microcrystals completely covering the (calcite?) matrix. This is a rare hydrated, calcium, manganese, sulfate, carbonate that comes out only rarely from the Kalahari Fields. It is the biggest and richest piece I have seen in awhile, probably from the 1980s, and is from the Phil Scalisi Collection.
