Description: Gold, Pyrite Locality: Brooklyn Mine, Brown's Gulch, Silverton, Silverton District, San Juan County, Colorado, USA (Locality at mindat.org) Size: 3.7 x 2.8 x 2.7 cm. How often does one find Wire Gold specimens, let alone on Pyrite matrix? This exceptionally rare and attractive association specimen is from the Brooklyn mine, which is just a few miles northwest of Silverton, in the San Juan Mountains of Colorado. The piece features several small but somewhat thick "wires" of bright Gold along with micro crystalline Gold on Pyrite matrix. To find Gold on Pyrite is rather uncommon in the mineral world, and specimens from this mine are seldom available. This piece came from the well-known Colorado collection of Richard A. Kosnar, and his label states that the piece was collected in May of 1980 by a miner named Ed Melka.
