The ring centres on an oval-cut natural sapphire of approximately 1.80 carats, surrounded by ten brilliant-cut natural diamonds totalling approximately 1.00 carat.\u003cspan class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eThe sapphire displays a deep royal-blue colour, with flashes of brighter blue visible as the stone catches the light. Its oval proportions are complemented by a closely set surround of well-matched diamonds, creating a defined and highly symmetrical cluster. The diamonds are set in platinum to enhance their white appearance, while the yellow-gold shank provides a traditional contrast characteristic of jewellery from this period.\u003c\/p\u003e\n\u003cp\u003eWith 1.00 carat of diamonds surrounding a richly coloured central sapphire, the ring has excellent presence while remaining elegant and wearable.
