Art Deco Sapphire and Diamond Halo Ring

Description

This Art Deco sapphire and diamond ring dates to the 1920s and features a cushion-cut blue sapphire framed by a square diamond halo. Crafted in 18ct yellow gold with a contrasting white metal top, it works beautifully as an engagement ring, right-hand statement ring, or September birthstone ring. The geometric plaque design reflects the clean symmetry and architectural lines that define true Art Deco jewellery.

Design & Craftsmanship

At the centre sits a richly coloured cushion-cut sapphire displaying a soft cornflower to mid-blue hue. Its crisp facets catch the light with every movement. Surrounding it, a border of old cut diamonds adds depth and period sparkle. Each diamond shows the slightly irregular faceting typical of hand-cut stones from the era, which gives the ring warmth and character. Fine milgrain detailing frames the square setting, while diamond-set shoulders taper elegantly toward the band. As a result, the ring feels balanced, refined, and unmistakably Deco.

Why We Love This Ring

This Art Deco sapphire and diamond ring feels bold yet wearable. The square diamond frame creates strong presence, while the cushion sapphire softens the overall look. It sits neatly on the hand and offers impact without excess height. Because sapphire symbolises loyalty and wisdom, it makes a meaningful choice for an engagement or anniversary.

Styling Ideas

Wear this antique sapphire ring alone for a clean vintage statement. Alternatively, pair it with a slim diamond band to enhance its sparkle. It also layers beautifully with other antique rings for a curated look. It suits someone with discerning taste who values craftsmanship over fast fashion and wants a  unique piece of jewellery with a story to tell.
