Item Description
Mineral specimens of ANY species are VERY RARE from this obscure Boulder County gold mine. Extremely large, for ANY Colorado locality, clusters of lustrous, silver-metallic sylvanite blades are visible on all five sides of this rich ore specimen. The spectacular large crystal spray is 2.9 cm long!! Undoubtably older material from the 1950s or possibly much older. Super rare, rich and fine large Colorado sylvanite. Ex Richard Hauck Collection. A MUST for the Colorado or species collector. Value???
