Gold, Hessite, Kutnohorite
A classic gold specimen from the famous Sunnyside mine in the renowned San Juan Mountains of southwestern Colorado. This piece features a predominant, rather unusual complex crystal (highly modified dodecahedron with octahedral faces) of gold with excellent luster and a bright color associated with massive black-grey hessite and pale pinkish color kutnohorite on white quartz matrix. The hessite on the specimen was analyzed by Gene Foord in the early 1980s. The piece is from the famed Colorado Gold collection of Richard A. Kosnar, and his label accompanies the piece. According to the label, the piece was mined in 1978, and Rich purchased the piece in 1983 after the Sunnyside Mine was shut down for over a year when Lake Emma collapsed and flooded the entire mine from the top down. A great Gold specimen from this now defunct, but highly significant Colorado Gold mine. From the D Level, Little Mary Vein.
