Art Deco Cornflower Blue Sapphire & Diamond Ring in 9ct Yellow Gold & Platinum, Circa 1930–40s

A beautiful Art Deco sapphire and diamond ring dating to circa 1930–40s, featuring a vibrant cornflower blue sapphire set within an elegant geometric design, crafted in 9ct yellow gold with a platinum-topped setting.

At the centre is a square-cut natural sapphire, displaying a captivating cornflower blue hue. The sapphire is set diagonally in a diamond-shaped orientation, framed by a delicately scalloped platinum surround that beautifully complements its rich blue colour.

Flanking the central sapphire are two small rose-cut natural diamonds, each nestled within decorative, leaf-shaped platinum settings. The intricate detailing and symmetrical arrangement are characteristic of the Art Deco period, combining geometric elegance with delicate ornamental touches.

The platinum-topped setting provides a lovely contrast against the warm yellow gold shank, which tapers gracefully towards the shoulders. With its beautifully balanced proportions and distinctive period design, this charming ring is a wonderful example of Art Deco jewellery.

Presented in excellent condition, this timeless piece would make a lovely addition to an antique jewellery collection or a distinctive everyday ring.
