Sphalerite on Siderite (RARE locale!) Trimingham Coll.

Item Description

Over a dozen clusters of translucent, dark red, rubyjack sphalerite crystals are aesthetically scattered on the mounded matrix covered with tan, flattened, siderite rhombs. This is EXTREMELY RARE, possibly unique combination material from King County, as MINDAT does not list this strikingly named prospect. Ex Bob Trimingham Collection and purchased from well-known Washington field collector, scientist and dealer, Bart Cannon, who collected the piece in 1982.
