A dream of the Art Deco era, this two-tone ring marries glowing 18ct Yellow Gold with cool Platinum settings. At its heart, a bright 1.00ct Old European-Cut Diamond sits proudly in a raised multi-prong basket, flanked by tapered, pavé-set Diamond shoulders edged in fine milgrain. An elegant openwork gallery completes the look, lending that airy, refined Deco poise we adore.

Graded I/J colour and SI1 clarity, the centre stone has fabulous presence and lively fire, its crisp facets beautifully framed by the Platinum head and the polished Gold shank. Later re-hallmarked in London in 2024, she remains every inch a c.1930s beauty—romantic, timeless, and made to be worn and treasured.
