Iridescent Sphalerite

Item Description

This is very rare stuff, from a one-time find at the Elmwood from which Rob bought a flat of specimens way back in his early days, and held onto ever since. Sphalerite from the Elmwood is common (it is the zinc or that was the reason for the mine), but these crystals are iridescent, throwing off shimmering colors! Note the cute little purple fluorite.
