Epidote and Chalcopyrite

Unknown Owner

The colour, habit and structure of this fine Epidote lends an appearance more of plant than mineral, forming undulating spiky mounds of deep moss-green over a hidden, green-tinged Quartz matrix. From the cobalt-iron deposit at Dashkesan in Azerbaijan, the Epidote forms acicular crystals to 4 or 5 mm tall; individually of translucent lime green yet grading to a dark mossy-green as a clustered mass of crystals. At one side, attached to the thin Quartz matrix plate is a solitary, 1.6 cm long Chalcopyrite crystal with a dark grey and green patina.
