{"product_id":"quartz-epidote-and-microcline-var-adularia","title":"Quartz, Epidote, and Microcline Var. Adularia","description":"\u003cp\u003eA remarkable quartz, microcline variety adularia, and epidote thumbnail specimen from the historic Mass C shaft in Ontonagon, Michigan. I acquired this piece from Karl Schaffer who collected it in the early 70s when he and his friends were exploring the now inaccessible Mass Mine. The piece features peach-colored microcline crystals, colored by disseminated copper, strikingly contrasted against milky quartz and green epidote. A unique and hard to come by piece of Michigan's rich mining history.\u003cbr\u003e\u003c\/p\u003e","brand":"Adamantine Minerals","offers":[{"title":"Default Title","offer_id":53045180104977,"sku":"Cu33","price":20.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0900\/2277\/3009\/files\/il_1588xN.6763735968_m429.webp?v=1768949290","url":"https:\/\/adamantineminerals.com\/products\/quartz-epidote-and-microcline-var-adularia","provider":"Adamantine Minerals","version":"1.0","type":"link"}
