A member of the Feldspar group, Oregon Sunstone is prized for its lively optical phenomenon caused by flat, reflective copper inclusions contained within the stone. This distinctive sparkly luster is known as \u003cem\u003eaventurescence\u003c\/em\u003e — commonly referred to as \u003cem\u003eSchiller\u003c\/em\u003e — and gives each stone a dynamic, light-catching quality unlike any other gem.\u003c\/p\u003e\u003cp\u003eOregon Sunstone is expensive to mine: a ton of raw rock typically yields only about a pound of Sunstone, and only a fraction of that reaches gem quality. These 6x4mm oval cabochons are Fine Quality stones — transparent to semi-transparent — displaying a body color ranging from light orange to light red, with aventurescence throughout. Some stones exhibit attractive bi-color characteristics, adding further individuality to each piece.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNatural Oregon Sunstone\u003c\/strong\u003e — mined in Oregon, USA with no treatments applied\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFine Quality\u003c\/strong\u003e — transparent to semi-transparent clarity\u003c\/li\u003e\n\u003cli\u003eDistinctive \u003cstrong\u003eaventurescence (Schiller effect)\u003c\/strong\u003e produced by flat copper inclusions\u003c\/li\u003e\n\u003cli\u003eBody color ranges from \u003cstrong\u003elight orange to light red\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eSome stones display \u003cstrong\u003ebi-color characteristics\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eCut in a \u003cstrong\u003e6x4mm oval cabochon\u003c\/strong\u003e shape\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eGem Type\u003c\/th\u003e\n\u003ctd\u003eOregon Sunstone (Feldspar group)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eShape\u003c\/th\u003e\n\u003ctd\u003eOval Cabochon\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSize\u003c\/th\u003e\n\u003ctd\u003e6x4mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eQuality Grade\u003c\/th\u003e\n\u003ctd\u003eFine Quality\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eClarity\u003c\/th\u003e\n\u003ctd\u003eTransparent to Semi-Transparent\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBody Color\u003c\/th\u003e\n\u003ctd\u003eLight orange 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\u003eInclusions\u003c\/th\u003e\n\u003ctd\u003eFlat reflective copper inclusions\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\u003eOrigin\u003c\/th\u003e\n\u003ctd\u003eOregon, USA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eNotes\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eNatural gemstones exhibit variation in color, tone, and pattern — individual stones may differ from images shown.\u003c\/li\u003e\n\u003cli\u003eSome stones in this lot may display bi-color characteristics.\u003c\/li\u003e\n\u003cli\u003eAventurescence intensity may vary from stone to stone.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Otto Frei","offers":[{"title":"Default Title","offer_id":44029491183830,"sku":"935-720","price":24.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/fine-quality-6x4mm-oval-sunstone-cabochon-otto-frei.jpg?v=1719954302","url":"https:\/\/www.ottofrei.com\/products\/oregon-sunstone-cabochon-oval-6x4mm-fine-quality","provider":"Otto Frei","version":"1.0","type":"link"}
