{"product_id":"huge-oregon-sunstone-rose-cut-oval-13773","title":"HUGE Oregon Sunstone Rose Cut Oval | 17.5x13.3mm, 11.6ct | Sun Crystal Mine | OSR108","description":"\u003cp\u003eAt 17.5x13.3mm and 11.6 carats, this rose cut oval is genuinely large for an Oregon Sunstone - stones of this size are uncommon in the market, and finding one in a rose cut adds another layer of rarity since the cut requires substantial depth to execute well. This one sits at 8mm deep, and that depth is doing real work: it gives the schiller - that metallic, light-scattering phenomenon caused by copper platelets suspended within the crystal - room to express itself, producing a soft peach sparkle that moves with the stone. The color is pale peach throughout.\u003c\/p\u003e\n\u003cp\u003eOregon Sunstone is the only North American feldspar with gem-quality schiller, and its domestic origin has made it increasingly appealing to designers working with provenance-conscious clients. The schiller intensity and color saturation vary stone to stone depending on copper content, which means each piece has a genuinely individual character. Feldspar has perfect cleavage in two directions, so it warrants a protective setting style - bezels and low-profile prongs are worth considering, especially for a stone this size.\u003c\/p\u003e\n\u003cp\u003eThis stone is untreated. The pale peach color and schiller are entirely natural, with no heat, irradiation, or filling of any kind.\u003c\/p\u003e\n\u003cp\u003eDIMENSIONS\u003cbr\u003e\nSize: 17.5mm x 13.3mm x 8mm\u003cbr\u003e\nWeight: 11.6 ct\u003c\/p\u003e\n\u003cp\u003eSTONE DETAILS\u003cbr\u003e\nVariety: Oregon Sunstone - Rose Cut\u003cbr\u003e\nSpecies: Feldspar\u003cbr\u003e\nCut: Rose Cut, Oval\u003cbr\u003e\nTreatment: None\u003cbr\u003e\nHardness: 6 – 6.5 Mohs\u003cbr\u003e\nRI: 1.560 – 1.572\u003c\/p\u003e","brand":"Gem Enthusiast","offers":[{"title":"Default Title","offer_id":47794292687035,"sku":"OSR108","price":260.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0639\/8214\/1627\/files\/huge-oregon-sunstone-rose-cut-oval-175x133mm-116ct-sun-crystal-mine-osr108-5492932.jpg?v=1778282173","url":"https:\/\/gementhusiast.shop\/products\/huge-oregon-sunstone-rose-cut-oval-13773","provider":"Gem Enthusiast","version":"1.0","type":"link"}
