Platinum Opal & Diamond Ring

A 5.08 carat opal cabochon in a warm honey body, lit from inside by play-of-colour — greens and oranges that shift as your hand moves. No two opals do this the same way; this one is genuinely alive in the light.

It sits in platinum — the metal estate jewellers reach for when they want the setting to disappear and the stone to do the talking — framed by 0.31 ct of round brilliant diamonds that trace the halo and run down the shoulders.

Living with an opal

Opal is softer than a diamond or a sapphire and holds a little water, so it is a piece to wear rather than to work in — off before the gym, the garden and the washing-up, and stored away from a hot window. Treated that way it will outlive all of us. We would rather tell you that now than have you find out later.

The Finish

Each piece ships in a Bizak & Co. presentation box, fully insured and signature-required, with a certificate of authenticity. Exact carat weights, gold karat and ring size are confirmed in writing on request — examined personally by a trained gemologist.

Photographs flatten an opal — the play-of-colour is stronger in the hand than on a screen. Viewing at the Seybold Building in Miami is welcome, and we will size it for you. Make an offer above or message us on WhatsApp.
