The historic Tiger locality, within Arizona's Mammoth–St. Anthony Mining District in Pinal County, is known for its diverse secondary copper minerals. Dioptase forms in the oxidized zones of copper deposits, where copper-bearing solutions interact with silica-rich environments. This vintage-labeled specimen offers an attractive example of Arizona's mineralogical heritage, combining vivid color, delicate crystal development, and historic locality provenance.\u003c\/span\u003e\u003c\/p\u003e","brand":"The Crystalary","offers":[{"title":"Default Title","offer_id":67782148292739,"sku":"barrydwr9-2of2-215","price":89.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0390\/4634\/8931\/files\/IMG_30813.jpg?v=1791933187","url":"https:\/\/www.thecrystalary.com\/products\/phenakite-phenacite-minas-gerais-brazil-copy","provider":"The Crystalary","version":"1.0","type":"link"}
