16hhdm.nr ((CORNWALLITE, CONICHALCITE, GYPSUM)), $60 MINIMUM BID, Gold Hill Mine, Tooele County, Utah, 15 x 13 x 3 cm, Cabinet | |
This specimen came out of a local collection but was not labeled. It looks like a typical large Gold Hill specimen. Dark green botryoidal mounds cover the from and back side with some variation and also bright color and wet like luster from areas probably covered with Gypsum. It is probably a combination of Cornwallite, Conichalcite and associated arsenates. |
