14hhjwis ((GYPSUM)), $15 MINIMUM BID, Hidden Treasure Mine, Ophir District, Tooele County, Utah, 12 x 11.5 x 1.5 cm, Cabinet, | |
Here is a large thinner specimen with lustrous multicrystalline Gypsum covering both sides. Usually Gysum coats something else such as Smithsonite or Hemimorphite. However looking at the edges I do not see any other species. Photos do not do justice to the multi faces of the Gypsum coating reflecting from the multiple faces. ex Jim Willson circa 1990. |
