18ct Oval Opal and Diamond Cluster Ring

A striking vintage opal and diamond cluster ring centred with an oval cabochon natural opal, displaying soft play-of-colour across its surface. The opal weighs approximately 0.70 carats and is framed by a generous halo of brilliant-cut diamonds totalling approximately 1.00 carat, adding exceptional brightness and contrast.

Crafted in 18ct yellow gold, the cluster head measures approximately 14 × 16mm, giving the ring a bold yet balanced presence on the hand. The diamonds are graded SI clarity, offering lively sparkle that beautifully enhances the opal’s luminous character.

This classic cluster design is emblematic of vintage jewellery, combining warmth, elegance, and visual impact. A timeless statement ring, equally suited to evening wear or as a distinctive engagement or cocktail ring.
