Provenance
Original to c.1910, this Edwardian cluster is a true showstopper of a ring. 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.
Surrounded 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.
