The old mine cut — the Victorian precursor to the modern brilliant — has a distinctive cushion outline and a deeper pavilion than its contemporary equivalents, producing a warmer, more romantic quality of light that is increasingly prized by collectors and wearers who want something with genuine period character. This is a particularly clean and well-proportioned example of the type.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe diamond sits in a simple claw collet on a plain polished yellow gold shank, stamped 18ct, in a design that lets the stone speak entirely for itself. Ring size is P and condition is very good throughout. A timeless antique engagement or dress ring with the quiet confidence of a piece made to last.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e \u003c\/p\u003e\n\u003chr class=\"border-border-200 border-t-0.5 my-3 mx-1.5\"\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eDetails\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul 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\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eMetal: 18ct yellow gold\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eHallmarks: 18ct stamp\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eOrigin: UK\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eEra: Antique, c.1900\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eStone: 0.28ct old mine cut diamond, H colour\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eSetting: Claw collet solitaire\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eDimensions: 6mm x 7mm\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eRing size: P\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eCondition: Very good\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"18ct Yellow Gold","offers":[{"title":"Default Title","offer_id":57989624463709,"sku":"SAO69","price":850.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0887\/0471\/3053\/files\/SAO69C_copy_d7b4ac15-4bde-404d-a161-5d275ea9385c.jpg?v=1752084129","url":"https:\/\/www.spectrumantiques.com\/products\/antique-18ct-yellow-gold-old-mine-cut-diamond-solitaire-ring-c-1900","provider":"Spectrum Antiques","version":"1.0","type":"link"}
