This is such a cool old-timer! It is a series of flattened crystals of native copper that formed in joint planes between blocks of basalt. It is old and oxidized. It came out of an old collection, dating from the 1920's. The catalogue was lost and this is the only info that I have on the specimen! Very cool.
