The Duftite\/Mimeite combination reminds us of classic Tsumeb material. \u003cbr\u003e\u003cbr\u003eDuftite is a lead-copper arsenate mineral with the formula PbCu(AsO4)(OH), belonging to the Adelite-Descloizite Group. It was named in 1920 by Otto Pufahl for Gustav Bernhard Duft, the second General Manager of the Tsumeb Mine in Namibia. This olive-green mineral typically forms botryoidal crusts and is a compositional intermediate in the conichalcite-duftite series.\u003cbr\u003e\u003cbr\u003eThe Ojuela Mine in Mapimí, Durango, Mexico is a world-class locality discovered in 1660 and renowned for producing the finest adamite specimens globally, characterized by lemon-yellow crystal aggregates in wheels and balls on reddish brown limonite matrix. This active group of mines is also the type locality for ojuelaite, a zinc-iron arsenate mineral named specifically for this site. Collectors prize the mine for its exceptional output of high-quality adamite, including rare cobaltian and manganoan varieties that have fetched thousands of dollars at auction. The locality remains highly relevant today as a premier source for these iconic specimens, with hundreds of fine examples produced since the 1960s.\u003c\/p\u003e","brand":"Crystal Castle","offers":[{"title":"Default Title","offer_id":49101821247643,"sku":null,"price":26.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0336\/3012\/6217\/files\/212b07c5-b322-4b05-89dd-a40962aec684.jpg?v=1785099736","url":"https:\/\/www.overtonfamilyjewels.com\/products\/auction-win-a78beae3-75fc-46b0-9a5a-c2a863ea305d","provider":"OFJ's Crystal Castle","version":"1.0","type":"link"}
