Gladite (very rare) (polished)

Item Description

Gladite is a rare lead copper bismuth sulfosalt species, that was named after the Gladhammar Mines in Sweden. The species is part of the Aikinite-Bismuthinite series (for reference, we actually have a specimen of Aikinite available in this week's auction so be sure to check it out as well), but specimens are rarely seen on the market. This piece comes from the Peace of Mine Group in Idaho, and features a rich patch of dark grey metallic Gladite which has been sliced and polished to better show the quality. We've never had a piece of this material to offer in the auctions, and if you're a fan of rare minerals, sulfides / sulfosalts or minerals of the Western United States, don't pass this one up. From the worldwide collection of David Burgess (1951-2016). David was a prolific species collector from Newington, Connecticut, and the namesake for the extremely rare cobalt arsenate species Burgessite, which he discovered. The piece also comes with a classic label from well-known rarities dealer, Josef Vajdak.
