Calaverite: Identification, Uses, and Meanings Yes Dirt
Calaverite is a telluride of gold (a compound between gold and tellurium), meaning that under hydrothermal conditions (heated water in the earth’s crust) minerals are oxidized and dissolved and gold or silver filaments replace them The resulting filaments form the crystals on the mineral’s surface with lengthwise striations throughoutType Locality: ⓘ Stanislaus Mine, Carson Hill Gold Mining Company Mines (Carson Hill Mines), Melones, Carson Hill Mining District (Melones Mining District), Mother Lode Belt, Calaveras Co, California, USA Closely related to krennerite Calaverite has no cleavage The perfect cleavage on krennerite is {001}Calaverite: Mineral information, data and localities 66 x 55 x 22 cm This is an unusually large plate of rare Calaverite (gold telluride) crystals from the classic Cripple Creek district, which hit its heyday over 100 years ago Interestingly, you can see bands of silver ore running through the matrix, too!
