A rare blue-green copper carbonate mineral found in small amounts in certain copper ore deposits.
Named after Cornwall, England, where it was first discovered in the 19th century; combines the place name with the mineral suffix -ite, following the tradition of naming minerals after their discovery locations.
Cornwall's tin and copper mining heritage is so legendary that even rare minerals discovered there get named after the region—this blue-green stone is basically a geological autograph from one of history's greatest mining centers.
