{"product_id":"nontronite-specimen-brazil-15","title":"Nontronite Specimen | Brazil","description":"\u003cp\u003eCollector-grade Nontronite specimen from Minas Gerais, Brazil, measuring 3.17\" L x 2.95\" W x 2.50\" H and weighing 138 grams. This is close to cubic, within half an inch across all three axes. Chartreuse-to-olive crust wraps the piece so that it presents equally well from any angle. The exact specimen photographed is the one supplied.\u003c\/p\u003e\u003cp\u003eAn iron-rich member of the smectite clay group, nontronite forms through hydrothermal alteration of iron-bearing host rock. The botryoidal texture develops as the clay slowly replaces the weathering parent material. Color runs from yellow-green to deep olive depending on iron content. Nothing has been applied to this piece.\u003c\/p\u003e\u003cp\u003eBecause this is a clay at Mohs 1-2, it belongs behind glass or on a stable shelf rather than in a pocket or a grid. No water, no oils, no ultrasonic cleaning. A soft dry brush is all it needs. Traditionally associated with grounding, endurance, and connection to the natural world.\u003c\/p\u003e","brand":"Beyond Bohemian","offers":[{"title":"Default Title","offer_id":51195164917796,"sku":"IND-NON-SPC-0015","price":55.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0768\/6107\/9588\/files\/nontronite-015-04_26b74673-c04e-405b-97c4-6cc3623c6ec9.png?v=1785474608","url":"https:\/\/beyondbohemian.com\/products\/nontronite-specimen-brazil-15","provider":"Beyond Bohemian","version":"1.0","type":"link"}
