The sapphires in this ring have been specially cut to tessellate together to form a radiating oval shape. Cutting natural untreated sapphires in this way is an extremely time consuming and expensive technique, especially as it would waste significant amounts of high-quality material. Setting them seamlessly as in the present ring, with no claws or collets visible between the stone, was a technique pioneered by some of the elite French jewellery houses of the early 20th century, particularly Van Cleef \u0026amp; Arpels, and would have required the skills of a master craftsman.\u003c\/p\u003e\n\n\u003ctable width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left;\"\u003e\u003cstrong\u003ePlace Of Origin\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"text-align: left;\"\u003eFrance\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left;\"\u003e\u003cstrong\u003eStone Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"text-align: left;\"\u003e\n\n\n\nSapphires: Approx. 1.10 carats total \u003cem\u003e(calculated)\u003c\/em\u003e\u003cbr\u003eAccompanied by GCS report no. 79232-23; stating that the sapphires are natural, with no indications of heat treatment\u003cbr\u003eCentral diamond: 0.35 carat \u003cem\u003e(calculated)\u003c\/em\u003e\u003cbr\u003eOther diamonds: Approx. 0.50 carats total\u003cbr\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left;\"\u003e\n\n\u003cstrong\u003eStone Dimensions\u003c\/strong\u003e\u003cbr\u003e\n\u003c\/td\u003e\n\u003ctd style=\"text-align: left;\"\u003eHeight of setting: 8.5mm\u003cbr\u003eDimensions of setting at front: 21mm x 14mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left;\"\u003e\u003cstrong\u003eMetal Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"text-align: left;\"\u003e18 carat yellow and white gold\u003cbr\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left;\"\u003e\u003cstrong\u003eMarks\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"text-align: left;\"\u003eFrench assay mark \u003cem\u003e(eagle’s head)\u003c\/em\u003e\u003cbr\u003ePartial French maker’s mark with Fleur de Lis and initial 'G'\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left;\"\u003e\u003cstrong\u003eDate Of Manufacture\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"text-align: left;\"\u003e1955 - 1965\u003cbr\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left;\"\u003e\u003cstrong\u003ePeriod Of Manufacture\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"text-align: left;\"\u003e20th Century \u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left;\"\u003e\u003cstrong\u003eCondition\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"text-align: left;\"\u003eVery good\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left;\"\u003e\u003cstrong\u003eSigns Of Wear\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"text-align: left;\"\u003eVery minor wear to mount commensurate with age\u003cbr\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left;\"\u003e\u003cstrong\u003eBand Size\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"text-align: left;\"\u003e\n\n\u003cspan\u003eUK O 1\/2 \/ US 7.5 \u003cem\u003e(complimentary re-size available)\u003c\/em\u003e\u003c\/span\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left;\"\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"text-align: left;\"\u003e\n\n5.42 grams \u003cem\u003e(gross)\u003c\/em\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Antique Ring Boutique","offers":[{"title":"Default Title","offer_id":32388599218311,"sku":"ARB-93","price":6370.0,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0310\/0442\/6375\/products\/ARB-93.jpg?v=1632667049","url":"https:\/\/www.antiqueringboutique.com\/en-au\/products\/art-deco-french-1930s-18ct-gold-diamond-and-calibre-sapphire-engagement-ring","provider":"Antique Ring Boutique","version":"1.0","type":"link"}
