Dioptase with Duftite on Calcite

Dioptase crystals of deep emerald green richly coat a bed of small rhombohedral Calcite crystals, some of which are included with apple green Duftite.  This miniature exudes Tsumeb because of the combination of these iconic minerals and it is well priced at $450.  There is one large Dioptase crystal which measures 1.3 cm long and this is surrounded by numerous 1 to 2 mm crystals which appear a bluish green due to more light passing through the prisms, reflected from the underlaying white Calcite.  A charming Dioptase on Calcite from Tsumeb.
