TX16H7: Dioptase
The main crystal, rising on a surface of smaller crystals, can be considered as a giant. Its faces and edges are perfectly defined, bright and partially pseudomorphed by another (undetermined) copper mineral. The matrix is a very rich blue mineral described as Chrysocolla on the label but it must be Plancheite. Please note that although the original labels state that the locality is "near Gouloukoutou River", we have labeled it as Tantara because we believe that this is the right locality.
The sample is with two old labels, of Burminco (George Burnham) and from D.E. Boydston collection.
