The oval-cut stone displays a rich blue of medium-strong saturation, its transparent body revealing subtle variations of light through a combination of brilliant and step-cut facets. Set horizontally within a substantial 18K yellow gold mounting, the sapphire is flanked by white diamonds, whose cool brilliance offers a deliberate contrast to the warmth of the surrounding metal.\u003c\/div\u003e\u003cdiv\u003eThe sapphire is accompanied by SSEF Report No. 157826, dated September 21, 2026, confirming its natural origin from Ceylon (Sri Lanka) and, importantly, \u003cstrong\u003eno indications of heating\u003c\/strong\u003e. The absence of detected heat treatment is a particularly desirable characteristic in fine sapphires, preserving the stone's natural color as an essential part of its gemological identity. Measuring approximately 11.40 × 9.05 × 4.45 mm, the sapphire possesses generous proportions that complement the ring's bold, geometric construction.\u003c\/div\u003e\u003cdiv\u003eDuring the 1980s, Bulgari developed an unmistakable design language centered on richly colored gemstones, substantial volumes of polished gold, and a confident departure from conventional diamond-dominated jewelry. This ring reflects that Roman sensibility, allowing the sapphire's saturated blue to remain the focal point while the broad gold shoulders create a powerful architectural silhouette. The restrained diamond accents lend definition without interrupting the purity of the composition.\u003c\/div\u003e\u003cdiv\u003eWeighing 15.11 grams and measuring a US size 8, the ring possesses a substantial yet carefully balanced presence on the hand, its smooth contours emphasizing the interplay between gemstone, metal, and light.\u003c\/div\u003e\u003cdiv\u003e\u003cem\u003eA single expanse of Ceylon blue, held within the quiet strength of Roman gold.\u003c\/em\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cstrong\u003eDetails\u003c\/strong\u003e\u003c\/div\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaker:\u003c\/strong\u003e Bulgari\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePeriod:\u003c\/strong\u003e 1980s\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMetal:\u003c\/strong\u003e 18K Yellow Gold\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStones \u0026amp; Carat Weight:\u003c\/strong\u003e Natural oval-cut blue Ceylon sapphire, previously listed as approximately 4.00 carats; white diamonds, carat weight not specified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSapphire Cut:\u003c\/strong\u003e Oval, mixed brilliant\/step cut\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSapphire Color:\u003c\/strong\u003e Blue of medium-strong saturation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSapphire Measurements:\u003c\/strong\u003e Approximately 11.40 × 9.05 × 4.45 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSapphire Origin:\u003c\/strong\u003e Ceylon (Sri Lanka), as confirmed by SSEF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTreatment:\u003c\/strong\u003e No indications of heating, as confirmed by SSEF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGemological Report:\u003c\/strong\u003e SSEF Report No. 157826, dated September 21, 2026\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRing Size:\u003c\/strong\u003e US 8; not sizable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 15.11 grams\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCondition:\u003c\/strong\u003e Excellent vintage condition\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal ID:\u003c\/strong\u003e RI65565\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Bvlgari","offers":[{"title":"Default Title","offer_id":67920313254161,"sku":"RI65565","price":59500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0905\/9008\/5393\/files\/IMG_0711_Product_Beautifier_4308957.jpg?v=1793307023","url":"https:\/\/www.odeoncollection.com\/products\/bulgari-no-heat-ceylon-sapphire-and-diamond-ring-in-18k-yellow-gold-1980s","provider":"Odeon Collection","version":"1.0","type":"link"}
