Classic Tsumeb Mine crystals of Dioptase are scattered and aggregated over the display face of the specimen. Inter grown lustrous colourless to white crystals of sharply formed rhombs of Calcite have formed on a reddish matrix, crystals of Calcite measuring to 0.5cm on edge. The Calcite forming a contrasting matrix for the Dioptase crystals. Well developed crystals of emerald green Dioptase measure to 1cm, have areas of light yellow-green crystallized Duftite mostly concentrated on their termination. A later deposition of micro-rhombic of slightly curve faced 'Dolomite' have formed on the Duftite and Dioptase.
