Set to centre with a natural precious black opal, cabochon-cut and rub-over set. This opal is without doubt the most magnificent opal we've ever had the joy of acquiring. It has the most stunning play-of-colour which is well distributed throughout the stone, predominant iridescence seen is green and blue, with every shade of the two possible coming to life as the stone is turned. The body colour is a rare and natural deep black which makes the greens and blues glow beautifully. There is such a magical quality to this opal. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eSurrounded by a cluster of transitional-cut diamonds, rub-over set and bordered by fine millegrain edging. The gallery features linear open-work and sits incredibly low on the finger - it is so comfortable to wear. The shoulders are very slightly open and feature swirling scrollwork intricately carved in platinum, flowing through to a solid platinum shank.\u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 dir=\"ltr\"\u003e\u003cspan\u003eThe Natural Stones\u003c\/span\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli dir=\"ltr\" role=\"presentation\"\u003e\n\u003cspan\u003e\u003cstrong\u003eOpal Weight:\u003c\/strong\u003e 5.80\u003c\/span\u003e\u003cspan\u003ect\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli dir=\"ltr\" role=\"presentation\"\u003e\n\u003cspan\u003e\u003cstrong\u003eOpal Size:\u003c\/strong\u003e \u003c\/span\u003e\u003cspan\u003eLength 15.5mm; Width 11.7mm; Depth 5.5mm\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli dir=\"ltr\" role=\"presentation\"\u003e\n\u003cstrong\u003eGem Certificate:\u003c\/strong\u003e\u003cspan\u003e Natural precious black opal; Cabochon-cut; Play of colour; No indications of treatment; Accompanied by GCS certificate \u003cem\u003e#5787-0394\u003c\/em\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli dir=\"ltr\" role=\"presentation\"\u003e\n\u003cspan\u003e\u003cstrong\u003eTotal Diamond Weight:\u003c\/strong\u003e \u003c\/span\u003e\u003cspan\u003e0.30ct; Round transitional-cut diamonds.\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 dir=\"ltr\"\u003e\u003cspan\u003eThe Band\u003c\/span\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli dir=\"ltr\" role=\"presentation\"\u003e\n\u003cspan\u003e\u003cstrong\u003eMetal Composition: \u003c\/strong\u003ePlatinum\u003c\/span\u003e.\u003c\/li\u003e\n\u003cli dir=\"ltr\" role=\"presentation\"\u003e\n\u003cspan\u003e\u003cstrong\u003eHallmarks:\u003c\/strong\u003e \u003c\/span\u003e\u003cspan\u003eMarked with 'PLATINUM', to indicate platinum.\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 dir=\"ltr\"\u003e\u003cspan\u003eThe Ring Overall\u003c\/span\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli dir=\"ltr\" role=\"presentation\"\u003e\n\u003cspan\u003e\u003cstrong\u003eFront Head Dimensions:\u003c\/strong\u003e \u003c\/span\u003e\u003cspan\u003eLength 20.4mm; Width 16.7mm\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli dir=\"ltr\" role=\"presentation\"\u003e\n\u003cspan\u003e\u003cstrong\u003eHeight of Setting:\u003c\/strong\u003e 5\u003c\/span\u003e\u003cspan\u003emm\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 dir=\"ltr\"\u003e\u003cspan\u003eGeneral Wear \u0026amp; Condition\u003c\/span\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli dir=\"ltr\"\u003e\n\u003cp dir=\"ltr\" role=\"presentation\"\u003e\u003cspan\u003e\u003cstrong\u003eExcellent:\u003c\/strong\u003e \u003c\/span\u003e\u003cspan\u003eall stones are secure and well set, with no damage to the mount.
