{"product_id":"nwa-7831-diogenite-fragment-11-01-g","title":"NWA 7831 - Diogenite - End Cut - 11.01g - Mali","description":"\u003cp data-start=\"26\" data-end=\"511\"\u003eNWA 7831 is a Diogenite, part of the HED Achondrite family strongly linked to asteroid 4 Vesta. It was found in 2013 near Chouichiyat in Saguia el Hamra, Western Sahara, as a single large mass of at least 20 kg, much of which fragmented during excavation. As a Diogenite, it represents material from deeper within Vesta’s crust or upper mantle, where minerals crystallised slowly before later impacts excavated and ejected the material into space. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"513\" data-end=\"1019\"\u003eSpecimens of NWA 7831 are known for their yellow-green crystalline material, often with pale orange weathering products along fractures. Prepared pieces can show a coarse, crystalline texture typical of Diogenites, dominated by orthopyroxene-rich material. Some fragments may retain weathered exterior surfaces, while cut faces reveal the mineral structure more clearly. Its colour and texture give it a distinctive appearance compared with many darker HED meteorites. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"1021\" data-end=\"1462\"\u003eFor collectors, NWA 7831 offers a visually interesting and well-documented Diogenite with a clear Vestan connection. Its large recovered mass, distinctive greenish crystalline appearance, and recognised classification make it appealing for collections focused on HED meteorites, Achondrites, or asteroid 4 Vesta material. Each specimen represents ancient slowly cooled asteroid material, later shaped by impact events and delivered to Earth.\u003c\/p\u003e","brand":"OuterSpacer Meteorites","offers":[{"title":"Default Title","offer_id":56250969227590,"sku":"DIO-16\/06","price":251.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0757\/0518\/8678\/files\/Diogenite783101-12.jpg?v=1774538988","url":"https:\/\/outerspacer.com\/products\/nwa-7831-diogenite-fragment-11-01-g","provider":"OuterSpacer Meteorites","version":"1.0","type":"link"}
