{"product_id":"nontronite-specimen-brazil-10","title":"Nontronite Specimen | Brazil","description":"\u003cp\u003eCollector-grade Nontronite specimen from Minas Gerais, Brazil, measuring 2.22\" L x 2.59\" W x 1.97\" H and weighing 56 grams. This is the smallest specimen in this group. Chartreuse botryoidal crust covers a compact nodule, bubble-like forms rendered small enough to read as a single rounded mass. The exact specimen photographed is the one supplied.\u003c\/p\u003e\u003cp\u003eNontronite is an iron-rich smectite clay in the phyllosilicate family. It forms where hydrothermal fluids alter iron-bearing rock, typically in the oxidized zones of nickel and iron deposits. The chartreuse to olive coloration comes from iron substituted directly into the clay structure. This specimen is untreated, with as-mined color and surface.\u003c\/p\u003e\u003cp\u003eNontronite is a clay mineral, which means water permanently alters its texture and color. Mohs 1-2 also makes it easy to mark with a fingernail. Keep it dry, dust with a dry natural-bristle brush, and store away from humidity. It is chosen for grounding and stability as a display piece.\u003c\/p\u003e","brand":"Beyond Bohemian","offers":[{"title":"Default Title","offer_id":51195164753956,"sku":"IND-NON-SPC-0010","price":22.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0768\/6107\/9588\/files\/nontronite-010-03_ea26b8ac-3b12-4686-8e57-764ba06efb78.png?v=1785474599","url":"https:\/\/beyondbohemian.com\/products\/nontronite-specimen-brazil-10","provider":"Beyond Bohemian","version":"1.0","type":"link"}
