Description:This is a wonderful blue-green Chrysocolla specimen replacing what was once either Azurite or Gypsum (depending upon whom you ask) from the famous Ray Mine in Arizona. The display side of this specimen is eye-catching showing excellent crystal form with SHARP faces. For a long time these specimens were labeled as Chrysocolla after Azurite, but nobody has been able to prove this, so some have speculated that they could be replacing Gypsum, which is also monoclinic in habit like Azurite. You don't see a lot of these pieces on the market, and they are certainly worth picking up if you collect pseudomorphs, secondary ore specimens or minerals from Arizona. This one has a bit of roughness in areas, so it's not 100% perfect, but it's really attractive in person and the sharpness of the pseudomorphs is very good. Priced at $500 retail. From the worldwide collection of noted Idaho collector Geary Murdock. Among other accomplishments, Geary was responsible for discovering some of the finest gem grade deep blue Aquamarine crystals in the Sawtooth Mountains of Idaho - which remain arguably the finest Aquamarines from any North American locality.
