Fashioned in 18K yellow gold with a contrasting white metal setting, the ring combines the bold proportions of late twentieth-century jewelry with the enduring elegance of a classical gemstone surround.\u003c\/div\u003e\u003cdiv\u003eThe sapphire displays a vivid, richly saturated blue, its modified step-cut facets revealing subtle variations of color and light across the stone. Measuring approximately 9.82 × 8.24 × 7.46 mm, the sapphire is estimated to weigh \u003cstrong\u003eapproximately 5.50 to 6.50 carats\u003c\/strong\u003e, based on its recorded dimensions and cutting proportions.

The diamonds are set within a softly squared white metal surround, contrasting with the broad, polished shoulders of the yellow gold shank. The ring’s substantial construction, weighing 15.2 grams, gives it a sculptural presence, while the smooth, tapering shoulders allow the design to sit naturally against the hand.\u003c\/div\u003e\u003cdiv\u003eThe sapphire is accompanied by a report from American Gemological Laboratories, dated October 26, 2026, confirming its natural origin from Ceylon (Sri Lanka). Particularly noteworthy is the laboratory’s finding of \u003cstrong\u003eno gemological evidence of heat treatment\u003c\/strong\u003e, an important characteristic in the appreciation of fine natural sapphires.\u003c\/div\u003e\u003cdiv\u003eSri Lanka has been celebrated for centuries as one of the world’s most important sources of exceptional sapphires, particularly stones distinguished by their luminous blue color. During the 1980s, French jewelers frequently embraced generous gemstone proportions and substantial gold settings, creating pieces that balanced traditional gemological refinement with a distinctly modern sense of scale. This ring reflects that aesthetic through its confident silhouette, architectural goldwork, and carefully considered relationship between sapphire and diamonds.\u003c\/div\u003e\u003cdiv\u003eThe combination of an unheated Ceylon sapphire, a brilliant diamond surround, and substantial French goldwork gives the ring a character that is both commanding and refined.\u003c\/div\u003e\u003cdiv\u003eA deep blue held within a circle of light, where color becomes the architecture of the jewel.\u003c\/div\u003e\u003ch3\u003e\u003cstrong\u003eDetails\u003c\/strong\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePeriod:\u003c\/strong\u003e 1980s\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrigin:\u003c\/strong\u003e France\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMetal:\u003c\/strong\u003e 18K Yellow Gold with White Metal Diamond Setting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrincipal Stone:\u003c\/strong\u003e Natural Blue Sapphire\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSapphire Origin:\u003c\/strong\u003e Ceylon (Sri Lanka)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSapphire Cut:\u003c\/strong\u003e Cushion Shape, Modified Step Cut\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSapphire Measurements:\u003c\/strong\u003e Approximately 9.82 × 8.24 × 7.46 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEstimated Sapphire Weight:\u003c\/strong\u003e Approximately 5.50–6.50 carats, calculated from dimensions; not independently verified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSapphire Treatment:\u003c\/strong\u003e No Gemological Evidence of Heat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiamonds:\u003c\/strong\u003e Round Brilliant-Cut Diamonds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTotal Diamond Weight:\u003c\/strong\u003e Approximately 1.27 carats\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDesign:\u003c\/strong\u003e Cushion-Shaped Sapphire within a Diamond Surround\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTotal Weight:\u003c\/strong\u003e 15.2 grams\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRing Size:\u003c\/strong\u003e US 6¾\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSignature:\u003c\/strong\u003e Unsigned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGemological Documentation:\u003c\/strong\u003e AGL Prestige Gemstone Report\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAGL Report Number:\u003c\/strong\u003e 1160434\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReport Date:\u003c\/strong\u003e October 26, 2026\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003e\u003cstrong\u003eGemological Documentation\u003c\/strong\u003e\u003c\/h3\u003e\u003cdiv\u003e\u003cstrong\u003eAmerican Gemological Laboratories (AGL)\u003c\/strong\u003e\u003c\/div\u003e\u003cdiv\u003eThe Prestige Gemstone Report\u003c\/div\u003e\u003cdiv\u003eDocument No. 1160434\u003c\/div\u003e\u003cdiv\u003eDated October 26, 2026\u003c\/div\u003e\u003cdiv\u003eThe report confirms:\u003c\/div\u003e\u003cul\u003e\n\u003cli\u003eNatural Corundum, Sapphire\u003c\/li\u003e\n\u003cli\u003eBlue Color\u003c\/li\u003e\n\u003cli\u003eCeylon (Sri Lanka) Origin\u003c\/li\u003e\n\u003cli\u003eCushion Shape, Modified Step Cut\u003c\/li\u003e\n\u003cli\u003eMeasurements: 9.82 × 8.24 × 7.46 mm\u003c\/li\u003e\n\u003cli\u003eNo Gemological Evidence of Heat\u003c\/li\u003e\n\u003cli\u003eNo Additional Enhancement Identified\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Odeon Collection","offers":[{"title":"Default Title","offer_id":67892854423825,"sku":"RI65581","price":19500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0905\/9008\/5393\/files\/Photoroom_20261027_170539_4368876.jpg?v=1793135616","url":"https:\/\/www.odeoncollection.com\/products\/1980s-french-ceylon-sapphire-and-diamond-ring-in-18k-yellow-gold","provider":"Odeon Collection","version":"1.0","type":"link"}
