Cumengeite

Cluster of deep blue Cumengeite crystals and white Anglesite on a green Chrysocolla matrix. There are two clusters of larger crystals (1.2cm wide and 1 cm wide) plus hundreds of tiny Cumengeite crystals sprinkled on the white Anglesite. This is a rare old specimen and uncommon even for Cumengeite as it it on a Chrysocolla matrix (as opposed to the more common clay matrix). Slight damage to the crystals on the larger cluster does not take away from the overall rarity and beauty of this specimen.
