Description

A reddish-coloured, ferruginous (?) matrix encrusted with colourless rhombohedral calcite crystals (to 1.5 mm) on which rest a very few minute sprays of malachite. Two larger second generation calcite crystals (to 20 mm), slightly flattened, translucent and honey-coloured, rest on the druse of smaller, colourless first generation crystals.

Neither the provenance nor the location in the mine are recorded.
