Why Benetoite Is So Expensive

Santa Barbara Museum of Natural History

Gene and Barbara Bilyeu, along with Galen Moyer and Bob Baker, took a detour into the wilds of Arizona northeast of Parker and paid a visit to the Planet Mine. This is a former copper mine which produced between 1863 and 1937. The remains of a few structures still stand and the entry portals to the mine shafts are covered with protective grates, but the site still features colorful minerals. The weather was rainy the day they were there, and they didn't stay too long, but they did come away with some attractive copper ore specimens.
