Description

A wonderful combination piece from this famous classic locality. Dioptase shows the very best quality you can imagine. All crystals are razor sharp terminated, gemmy and highly lustrous. The colour is much better in person and represents the very best colour for Tsumeb. The dioptase group is set exposed on snowy white calcite crystals. The ensamble could not be more aesthetic.
