At its heart is a large, high-domed 6.1ct bi-colour sapphire displaying a striking deep chromium green hue with flashes of teal blue. Surrounding the central sapphire is a halo of fourteen large rose-cut diamonds, each set in rubover silver settings, a hallmark of Georgian jewellery design.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eRose-cut diamonds, with their large triangular facets, were favoured during the Georgian and Victorian eras for their ability to glisten beautifully in candlelight. Unlike the closed-back and foiled settings typical of the period, these diamonds are unusually set in open-backed mounts, allowing light to pass through and enhancing their brilliance while also mitigating the buildup of dirt behind the stones—a common issue with foiled settings.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eSilver motifs adorn the shoulders, and the band, crafted in 18K gold, features a delicate Rococo-style pattern. The combined use of silver and gold, characteristic of 19th century craftsmanship, highlights the artistry of this piece. The rose-cut diamonds measure approximately 3mm in diameter.\u003cb\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cb\u003eDetails:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul class=\"ul1\"\u003e\n\u003cli class=\"li1\"\u003e\n\u003cspan class=\"s1\"\u003e\u003c\/span\u003eUK size L½ (US size 6)\u003c\/li\u003e\n\u003cli class=\"li1\"\u003e\n\u003cspan class=\"s1\"\u003e\u003c\/span\u003eRing weight: 7.69 grams\u003c\/li\u003e\n\u003cli class=\"li1\"\u003e\n\u003cspan class=\"s1\"\u003e\u003c\/span\u003eSapphire: Bi-colour, deep green with teal undertones (6.1ct)\u003c\/li\u003e\n\u003cli class=\"li1\"\u003e\n\u003cspan class=\"s1\"\u003e\u003c\/span\u003eDiamonds: Approx. 3mm in diameter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"p1\"\u003eThe ring remains in overall good condition for its age, with age-appropriate wear including some surface rubbing and patina to the gold and silver.
