Th. Böttger named it in 1839 after aurichalcum, the ancient Latin term for brass, reflecting its copper and zinc content. Its pale blue-green color commonly forms delicate crusts and feathery crystal tufts.\u003cbr\u003e\u003cbr\u003eOjuela Mine lies near Mapimí in Durango, Mexico, a historic group of mines first discovered in 1660 and renowned for its oxidized zinc- and arsenic-rich mineralization. It is world famous for exceptional adamite, particularly lemon-yellow wheel and ball aggregates on reddish-brown limonite, and has also produced hemimorphite, scorodite, calcite, and other colorful secondary minerals. The mine is the type locality for the rare zinc-iron arsenates ojuelaite and mapimite, adding special significance for collectors of species and type-locality material.\u003c\/p\u003e","brand":"Crystal Castle","offers":[{"title":"Default Title","offer_id":49783316283547,"sku":null,"price":26.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0336\/3012\/6217\/files\/3733a5b3-b8c6-4ece-92aa-ae3ef3cf8646.jpg?v=1791752942","url":"https:\/\/www.overtonfamilyjewels.com\/products\/auction-win-f5394a36-1e8d-40ff-9492-2c2a4d256209","provider":"OFJ's Crystal Castle","version":"1.0","type":"link"}
