{"product_id":"faceted-marquise-oregon-sunstone-natural","title":"Faceted Marquise Sunstone","description":"\u003cp\u003e\u003cstrong\u003eOregon Sunstone is a natural, all-American gem\u003c\/strong\u003e, sourced exclusively from mines in the state of Oregon and receiving no treatment of any kind. A member of the Feldspar mineral group, Oregon Sunstone is prized for its lively, sparkling luster caused by flat, reflective copper inclusions contained within the stone. This optical phenomenon — known as aventurescence and often referred to as \u003cem\u003eSchiller\u003c\/em\u003e — gives each stone a distinctive, glittering brilliance unlike any other gemstone.\u003c\/p\u003e\u003cp\u003eOregon Sunstone is transparent, with those same copper inclusions responsible for producing a warm reddish to golden and orange body color. These faceted marquise-cut stones exhibit high-end quality color ranging from orange to light red, making them an exceptional choice for fine jewelry fabrication and custom design work.\u003c\/p\u003e\u003cp\u003eOregon Sunstone is notably rare and labor-intensive to mine — a ton of raw rock typically yields only about a pound of Sunstone, with only a fraction of that reaching gem quality. Each stone is entirely natural and untreated, preserving the authentic character that makes Oregon Sunstone a standout among domestic gemstones.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eNatural Oregon Sunstone — no treatments of any kind\u003c\/li\u003e\n\u003cli\u003eAventurescence (Schiller) luster created by flat copper inclusions within the stone\u003c\/li\u003e\n\u003cli\u003eTransparent body color ranging from orange to light red\u003c\/li\u003e\n\u003cli\u003eHigh-end quality, faceted marquise cut\u003c\/li\u003e\n\u003cli\u003eAll-American gemstone, mined in Oregon\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eCut\u003c\/th\u003e\n\u003ctd\u003eFaceted Marquise\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOrigin\u003c\/th\u003e\n\u003ctd\u003eOregon, USA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTreatment\u003c\/th\u003e\n\u003ctd\u003eNone\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eColor Range\u003c\/th\u003e\n\u003ctd\u003eOrange to light red\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOptical Phenomenon\u003c\/th\u003e\n\u003ctd\u003eAventurescence (Schiller)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMineral Group\u003c\/th\u003e\n\u003ctd\u003eFeldspar\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eAvailable Options\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003ePart #\u003c\/th\u003e\n\u003cth\u003eSize\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e935-210\u003c\/td\u003e\n\u003ctd\u003e6x3mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e935-226\u003c\/td\u003e\n\u003ctd\u003e8x4mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Otto Frei","offers":[{"title":"6x3mm","offer_id":47551832522966,"sku":"935-210","price":30.0,"currency_code":"USD","in_stock":true},{"title":"8x4mm","offer_id":47551832555734,"sku":"935-226","price":90.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/faceted-marquise-sunstone-otto-frei.jpg?v=1719954548","url":"https:\/\/www.ottofrei.com\/products\/faceted-marquise-oregon-sunstone-natural","provider":"Otto Frei","version":"1.0","type":"link"}
