{"product_id":"7x5mm-faceted-octagon-oregon-sunstone","title":"7x5mm Faceted Octagon Sunstone","description":"\u003cp\u003eOregon Sunstone is a natural, all-American gem sourced exclusively from mines in the state of Oregon and has received no treatment of any kind. A member of the Feldspar group, Oregon Sunstone owes its distinctive lively glitter to flat, reflective copper inclusions contained within the stone. This sparkling optical phenomenon is known as \u003cem\u003eaventurescence\u003c\/em\u003e — commonly referred to as \u003cem\u003eSchiller\u003c\/em\u003e — and gives each stone a unique inner life.\u003c\/p\u003e\u003cp\u003eOregon Sunstone is notably rare and expensive to mine. A full ton of raw rock typically yields only about one pound of Sunstone, with only a fraction of that reaching gem quality. The result is a highly desirable stone prized by jewelers for its beauty and natural origin story. Oregon Sunstone is transparent, with copper inclusions responsible for producing a warm reddish to golden-orange body color. Some individual stones exhibit striking bi-color effects.\u003c\/p\u003e\u003cp\u003eThese 7x5mm faceted octagon Sunstones are high-end quality, ranging from orange to light red in color, and arrive completely untreated — ideal for custom jewelry applications where natural gemstones are specified.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eNatural Oregon Sunstone — no treatments applied\u003c\/li\u003e\n\u003cli\u003eFaceted octagon cut, 7mm x 5mm\u003c\/li\u003e\n\u003cli\u003eHigh-end quality stones\u003c\/li\u003e\n\u003cli\u003eColor range: orange to light red\u003c\/li\u003e\n\u003cli\u003eAventurescence (Schiller) effect from natural copper inclusions\u003c\/li\u003e\n\u003cli\u003eTransparent body with warm reddish to golden-orange hues\u003c\/li\u003e\n\u003cli\u003eSome stones exhibit bi-color characteristics\u003c\/li\u003e\n\u003cli\u003eMember of the Feldspar gemstone group\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eStone Type\u003c\/th\u003e\n\u003ctd\u003eOregon Sunstone\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCut\u003c\/th\u003e\n\u003ctd\u003eFaceted Octagon\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSize\u003c\/th\u003e\n\u003ctd\u003e7mm x 5mm\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\u003eTransparency\u003c\/th\u003e\n\u003ctd\u003eTransparent\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eColor\u003c\/th\u003e\n\u003ctd\u003eOrange to light red; some bi-colored\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\u003eInclusion Type\u003c\/th\u003e\n\u003ctd\u003eNatural copper inclusions\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\u003eGemstone Group\u003c\/th\u003e\n\u003ctd\u003eFeldspar\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Otto Frei","offers":[{"title":"Default Title","offer_id":44029490430166,"sku":"935-800","price":150.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/7x5mm-faceted-octagon-sunstone-otto-frei.jpg?v=1719954306","url":"https:\/\/www.ottofrei.com\/products\/7x5mm-faceted-octagon-oregon-sunstone","provider":"Otto Frei","version":"1.0","type":"link"}
