Dioptase on cornetite
description: LOCALITY: Unknown Mine, Katanga Province, Democratic Republic of the Congo 2" tall The lustrous, gemmy, pristine crystals of dioptase are perched on an esthetic blue matrix of cornetite with a felt like texture. I bought this piece in Lubumbashi in late 2009 during 3 weeks in spent there buying mineral specimens. Since I did not witness the mine site this piece was removed from, it is only possible to speculate which mine it came from.
