Dioptase from Morenci is a thing of rarity, and seldom do you see any large plates of quality. This is an extremely rare and fine example, with a solidly covered display face AND a pocket in the side that are completely filled with large crystals for the locale, and extremely rich coverage. The top surface features sharp little dioptaes against a sparkling druse of quartz, for contrast. Unusual! It is an important example of dioptase from a US locale, and many people aren't even aware they exist as they are just so hard to come by. Collected in the 1980s, and ex Harold Urish collection. MUCH BETTER In PERSON!
