Dioptase on cornetite
description: <p style="text-align: justify;">LOCALITY: Unknown Mine, Katanga Province, Democratic Republic of the Congo <br /><br />2" tall <br /><br />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. <br /> <br />This piece was bought from a supplier who lives in Katanga during a visit to Lubumbashi in late 2009. <br /> <br />Photo by Matthew Webb of Melbourne, Victoria, Australia</p>
