Three principal quatrefoil stations each hold an oval-cut sapphire at the centre — natural, unheated stones of basaltic origin totalling approximately 4.5ct — framed by rose-cut diamond accents totalling approximately 0.6ct, H colour, VS clarity. The connecting links continue the floral motif with further diamond points. Struck with French assay marks confirming the 18ct standard and origin. A romantic, wearable piece with genuine Belle Époque character, elevated by the quality of its natural, untreated sapphires.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cem\u003eDetails block:\u003c\/em\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\" class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3 print:block print:space-y-1\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e18ct yellow gold\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eFrench assay marks (eagle head)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003ePierced foliate scrollwork link design\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eThree sapphire and diamond quatrefoil stations\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eSapphires: approximately 4.5ct total, natural, unheated, basaltic origin\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eDiamonds: approximately 0.6ct total, H colour, VS clarity\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eSpring ring clasp\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eWeight: 21g\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eLength: 16.5\", 15mm at stations\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"18ct Yellow Gold","offers":[{"title":"Default Title","offer_id":65381690769757,"sku":"SAO472","price":0.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0887\/0471\/3053\/files\/11-02-26Lightbox-1403copy.jpg?v=1785076524","url":"https:\/\/www.spectrumantiques.com\/products\/art-nouveau-18ct-gold-sapphire-diamond-openwork-necklace","provider":"Spectrum Antiques","version":"1.0","type":"link"}
