GIA reports No Indications of Heating, meaning this is an untreated natural sapphire, and confirms the geographic origin as Yogo Gulch, Montana. Yogo sapphires are among the most sought-after American gemstones, prized for their naturally saturated cornflower blue color and for being untreated, which makes a GIA-certified unheated Yogo a rare and collectible stone. GIA designates the color as Blue with Transparent transparency. Buyers are encouraged to review all photos and the full GIA report carefully before purchasing.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecies:\u003c\/strong\u003e Natural Corundum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariety:\u003c\/strong\u003e Natural Sapphire\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight (Sapphire):\u003c\/strong\u003e 0.88 carats\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape:\u003c\/strong\u003e Oval\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCut Style:\u003c\/strong\u003e Brilliant Cut crown, Step Cut pavilion\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurements:\u003c\/strong\u003e 6.67 × 5.99 × 2.66 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Blue\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTransparency:\u003c\/strong\u003e Transparent\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTreatment:\u003c\/strong\u003e No Indications of Heating\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOrigin:\u003c\/strong\u003e USA (Yogo Gulch, Montana)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertification:\u003c\/strong\u003e GIA Sapphire Origin Report #2235897671 (verifiable at reportcheck.gia.edu)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMetal:\u003c\/strong\u003e 18K Gold\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSetting Style:\u003c\/strong\u003e Oval center stone with starburst round brilliant diamond cluster\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTotal Ring Weight:\u003c\/strong\u003e 5.10 grams (gross)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCondition:\u003c\/strong\u003e Pre-owned; excellent overall condition; prongs intact; all diamonds appear present and secure; no visible damage\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Lodems","offers":[{"title":"Default Title","offer_id":50107367260298,"sku":null,"price":1800.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0653\/3942\/4906\/files\/R19-1-2.jpg?v=1788112521","url":"https:\/\/6bd83a-a2.myshopify.com\/products\/gia-certified-unheated-montana-yogo-gulch-sapphire-diamond-18k-gold-ring","provider":"Lodems","version":"1.0","type":"link"}
