The shank appears to come from an earlier ring, probably c.1800 to 1820, and was reused for this cluster head around 1880, giving the ring a character unlike other examples. The gold tests as 21K, and it carries the French owl mark for imported gold.\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003eAn exceptional engagement ring.\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eDetails:\u003c\/strong\u003e c.1880, with an earlier shank c.1800–1820; gold testing 21K; unheated natural Ceylon sapphire, 5.71 ct, 13.37 × 9.43 × 5.27 mm (Bellerophon certificate); twenty cushion-cut diamonds approx. 3 mm; rose-cut diamond shoulders; 5.77g; UK O½, US 7¼.\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eCondition:\u003c\/strong\u003e Excellent.\u003c\/div\u003e","brand":"Ravensbury Antiques","offers":[{"title":"Default Title","offer_id":49368291770676,"sku":null,"price":13500.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0708\/6784\/5428\/files\/p14-02.jpg?v=1793973246","url":"https:\/\/ravensburyantiques.com\/en-je\/products\/ceylon-sapphire-cluster-ring","provider":"Ravensbury Antiques","version":"1.0","type":"link"}
