An elegant Art Deco Platinum Diamond solitaire, this ring centres on a natural antique Transitional-cut Diamond of approximately 0.65ct, graded around H colour and SI2 clarity. The centre is elevated in a refined setting with scalloped detailing, its sparkle beautifully echoed by graduated Diamonds set along the slender shoulders for a graceful, tapered silhouette.

Crafted in solid Platinum, the head shows charming period finishing with delicate beading and a pretty open gallery that lets the light flood through. A romantic detail, the band is inscribed “12-3-32”, a touchstone to its 1930s provenance. Utterly timeless, it’s a poised and poetic choice for an engagement ring or right-hand treasure.
