A very rich specimen of Pseudomalachite probably from Old Gunnislake Mine, Cornwall, from an old British collection. The matrix of Quartz crystals is heavily invested with light to mid-green minutely botryoidal Pseudomalachite. Specimens of this size or richness are very seldom seen from the mine with an old label attached to it.
