An Art Deco diamond solitaire ring in platinum, dating from approximately the 1920s to 1930s.

The central diamond, weighing approximately 1.39 carats, is an old European cut stone of excellent proportions. The old European cut — the immediate predecessor to the modern round brilliant — is prized today for its distinctive character: a higher crown, smaller table facet, and larger culet produce a play of light that is softer and more romantic than the precision-engineered flash of a contemporary diamond. In candlelight or warm light, these stones come alive in a way that modern cuts simply cannot replicate.

The setting is quintessentially Art Deco: geometric and architectural, with refined detail to the shoulders that is very much of the period. Platinum was the metal of choice for Art Deco jewellers — harder than gold, it allowed craftsmen to achieve finer milgrain edges and more delicate claw work while maintaining exceptional durability. It also complements the cool brilliance of a white diamond perfectly.

At 1.39 carats, this is a substantial diamond for the period, and the ring wears with quiet confidence — striking without being showy. It would make an outstanding antique engagement ring or a significant addition to a fine jewellery collection.

A superb vintage diamond three-stone ring in 18-carat yellow gold, set with three graduated old cut diamonds totalling approximately 1.82 carats. Three-stone rings — often called trilogy rings — carry a well-known symbolism: past, present, and future, making them one of the most enduringly popular choices for engagement rings and significant anniversaries alike.

What distinguishes this ring is the quality of the diamonds. Old cut stones of this size and total weight are increasingly rare — the larger the old cut diamond, the more pronounced its characteristic warmth and inner fire become. These three stones have been beautifully matched for tone and presence, and the graduated arrangement gives the ring a satisfying visual balance: a quietly impressive spread of light across the finger.

The setting is in 18-carat yellow gold, which provides a warm, rich contrast to the diamonds and is entirely in keeping with the vintage character of the piece. Yellow gold claw settings became less fashionable in the platinum era of the 1920s and 1930s, but they are very much back — and paired with old cut diamonds, the combination is particularly coveted by those who want something that feels genuinely different from modern fine jewellery.

An outstanding choice for an antique engagement ring, a significant anniversary gift, or a collector looking for a ring that will be treasured across generations. Condition is excellent.

Unusual Art Deco diamond ring, designed as a pierced flower or snowflake cluster, set throughout with old mine cut diamonds totalling approximately 0.70 carats. Old mine cuts — the hand-fashioned forerunner of the modern brilliant — have a warmer, softer sparkle than contemporary diamonds. The stones are evenly matched and set across a pierced, scalloped mount with open gallery work between each stone group, giving the ring an airy, architectural quality that is very characteristic of the period. A slightly larger centre stone anchors the design, surrounded by four groups of smaller stones at the cardinal points and further stones filling the outer edge.

The construction is two-tone: a platinum top with an 18ct yellow gold shank — a combination that was common in the transition between the Edwardian and Art Deco periods, when platinum was prized for its strength and whiteness in setting diamonds but gold remained the preferred metal for the band.
