Copper (Spinel Twinned)
This is a twinned, elegant copper from the famous Czar shaft at Bisbee. It would have been collected prior to the mid 1900s (probably closer to 1900 than not), and Frank later obtained it from a fellow miner's collection. The large spinel-twinned crystal in the middle is over 4 cm long. This is a fine copper from the core copper suite of the Valenzuela, Frank collection. His best suite is probably his wide copper collection, with focus on historic Arizona locales. Seldom does he part with a copper of any kind in trades or sales. This piece has never been cleaned and retains its original patina Joe Budd Photos.
