Galena with Sphalerite (rare locality specimen)

Item Description

A remarkable locality specimen from Crested Butte, certainly the best of its kind that we've seen. Specimens from the Keystone Mine are virtually impossible to find on the market, and if you collect Colorado minerals, or rare locality pieces, this is something you may not see again anytime soon. Small, grey cuboctahedral crystals of Galena measuring to about 4 mm are associated with black modified tetrahedral crystals of Sphalerite measuring up to 7 mm, with minor Pyrite and Quartz to create a showy overall display specimen. Most of the crystals are in good condition, though there are some areas of roughness that can be seen, but it's an important piece for the locality alone, and the fact that it features plenty of euhedral, well-formed crystals make its collector quality. A real treat to see something like this, but it's kind of piece that only exists in an extensive, eclectic collection like this.
Ex George Loud Collection No. 2611 CO.8; 6388. George (born August 16, 1942) is a well-known mineral collector from Washington, DC and South Carolina respectively, and was a patent lawyer by trade for over 50 years. He assembled one of the great mineral collections in the U.S., comprising worldwide specimens, and in later years he sold the worldwide specimens to focus on minerals of the United States, specifically locality suites with an emphasis on amazing representation of species while still maintaining fine quality. The specimens remarkably range from micros to all the way up to large cabinets in size. We recently acquired most of his impressive 9000+ piece collection, and the VAST majority of these pieces will be offered here in the auctions, as we feel that everyone deserves and equal opportunity at acquiring these important, well-documented and fine quality specimens for their collections.
