{"product_id":"nontronite-specimen-brazil-23","title":"Nontronite Specimen | Brazil","description":"\u003cp\u003eCollector-grade Nontronite specimen from Minas Gerais, Brazil, measuring 4.08\" L x 2.61\" W x 2.74\" H and weighing 338 grams. This is the longest piece in this group at 4.08 inches. Olive botryoidal crust runs the full span, thinning toward one end where the host rock shows through. 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":51195165179940,"sku":"IND-NON-SPC-0023","price":101.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0768\/6107\/9588\/files\/nontronite-023-06_c1661f7e-77fb-416f-93ec-7ee7b7554cc1.png?v=1785474627","url":"https:\/\/beyondbohemian.com\/products\/nontronite-specimen-brazil-23","provider":"Beyond Bohemian","version":"1.0","type":"link"}
