Cordierite, Anhydrite & Chalcopyrite (Ian Nicklin Coll.)

Item Description

Cordierite is one of those species condemned to exist in only ugly specimens of largely crude crystals. Here, however, from an obscure locality I hadn"t even heard of before, we have a wild exception to the trend! These robust crystals to 1.2 cm in size have a jet black color, waxy luster, and excellent crystal form! They are embedded and partially excavated from glassy, lavender, anhydrite and massive, golden, chalcopyrite to set off the crystals even more starkly. A very rare combination from this much less well-known copper-zinc-silver mine. Ex Ian Nicklin Collection, and he is now a curator at the Royal Ontario Museum.
