ID: CC21581
Spherical crystals of Chalcopyrite up to 1 cm in diameter form a mound of Blister Copper from Tincroft mine in Illogan, a parish close to Redruth in Cornwall.  The Blister Copper, a botryoidal variety of Chalcopyrite, is overgrown by 1 to 3 mm, slightly curved Chalcopyrite crystals and possibly some Siderite, all coated in a sooty black oxidation product.  This is a rich representative specimen of Blister Copper from this most famous locality, once the very heart of Cornish metalliferous mining.
