Sphalerite with Arsenopyrite and Pyrite

Item Description

An attractive sulfide association specimen from Chichibu featuring crystal groups of black Sphalerite, which measure up to 1.2 cm across, are intergrown with small, silvery-grey colored metallic Arsenopyrite crystals to a few mm along with minor "needles" of white Quartz and small lustrous light golden metallic Pyrite. Soft pinkish-beige colored semi-spherical aggregates of Calcite make for a nice contrast against the darker colored sulfides. The front/display side of the piece is in good shape, with no major damage I can find.
Ex George Loud Collection No. 5692; 2621 JA.2. 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.
