Art Deco Square Set Old Cut Diamond Solitaire Ring

Description

This Art Deco old cut diamond ring features a 0.95ct diamond with VS1 clarity and H colour, set in 18ct white gold and platinum. It dates to the Art Deco period and works beautifully as an  antique engagement ring or a refined everyday solitaire. The old cut diamond sits in a square platinum setting, which gives the ring strong geometry and a clean antique profile. It also comes with a full GIA affiliated certificate.

Design & Craftsmanship

A square platinum mount frames the diamond and gives the ring its crisp Art Deco character. Fine milgrain detail traces the edge of the setting and adds subtle texture without overwhelming the design. The open gallery allows light to move through the stone, which helps bring out its natural brightness and lively facet pattern. The slim 18ct white gold shank keeps the proportions elegant and easy to wear. The band carries an 18CT & PLAT stamp, confirming the use of 18ct white gold and platinum.

Why We Love This Ring

This antique solitaire ring has the clean structure many buyers want in an Art Deco diamond ring, yet the old cut stone gives it warmth and individuality. The 0.95ct size offers strong presence on the hand while still feeling practical for daily wear. Its VS1 clarity and H colour add to that appeal, because they offer a bright and well-balanced look. This is a strong choice for someone who wants period craftsmanship, lasting quality, and a solitaire with genuine character.

Styling Ideas

This Art Deco old cut diamond ring suits someone who values antique craftsmanship but prefers a simple and tailored look. It makes an excellent engagement ring, although it would also suit a buyer building a wearable vintage jewellery collection. The square setting gives it definition when worn alone, while the slim band allows it to sit neatly beside a wedding band or fine eternity ring. Its white metal finish also pairs easily with both antique and modern pieces.
