This classic 1950 ring is a vintage 18ct yellow gold cluster piece featuring an oval cabochon cut opal at the centre, surrounded by a halo of fourteen round brilliant cut diamonds with a total weight of 0.30 carats. The central opal displays iridescent white play-of-colour alongside orange, greens, blues and reds, held securely in traditional claw settings. The shoulders of the ring have a textured, carved finish that frames the central cluster on the polished yellow gold band. The face of the ring measures 1.2 cm wide by 1.5 cm high, with a total weight of 4.5 grams and a UK size K. Well-suited for formal evening wear or as an everyday statement piece on the hand, this item brings mid-century elegance to modern jewellery collections. The hallmarks stamped inside the band confirm its 18ct gold composition, while the intricate mounting and textured metalwork demonstrate the craftsmanship of the period. It fits comfortably as a standalone accessory or paired with other fine gold rings, adding a touch of vintage character and colour to any outfit.

FAQs

A cluster ring features a central focal gemstone surrounded by a halo of smaller gemstones, such as diamonds, designed to accentuate the central stones scale and optical properties.

These rings typically feature solid yellow or white gold, often in 18ct purity, securing a cabochon-cut natural opal alongside claw-set accent diamonds.

Genuine pieces bear official assay hallmarks indicating metal purity, while natural opals display an irregular, three-dimensional play-of-colour rather than repetitive printed patterns.

An opal cluster ring functions as a standalone statement piece on the hand or can be coordinated with plain gold bands and subtle diamond earrings.

Opals are porous gemstones that require gentle wiping with lukewarm water, avoiding submersion, harsh chemicals, extreme temperature changes, or ultrasonic cleaning devices.
