This 1920 Art Deco solitaire ring is fashioned from 18ct yellow gold and platinum. The shank displays a bright golden hue, whilst the central cushion cut diamond of 0.25ct sits within a silvery platinum claw setting embellished with detailed sculptural shoulders. Hallmarks stamped into the band indicate the metal standards of 18ct and Plat. The piece measures 0.5 cm high, 0.8 cm wide and 2 cm deep. Today, the ring serves as an engagement ring or a dress ring for daily wear on the hand. The mixed metals provide a striking contrast between the warm yellow gold band and the cool, bright setting holding the sparkling diamond. The delicate decorative work on the shoulders frames the central stone, giving the ring its distinctive period character.

FAQs

Art Deco jewellery, produced primarily during the 1920s and 1930s, is characterised by geometric shapes, clean lines, and the contrasting use of precious metals such as platinum and yellow gold alongside brilliant gemstones.

Art Deco solitaire rings frequently featured hand-cut diamonds set in platinum settings mounted on 18ct yellow or white gold bands, utilising claw or bezel mountings to maximize light reflection.

Authentic Art Deco rings typically display hallmarks denoting metal purity, hand-cut stone facets like Old European or cushion cuts, and intricate metalwork along the shoulders and setting.

An Art Deco diamond ring functions as a classic focal piece that pairs effortlessly with minimalist everyday wear or modern formal attire, layering well alongside sleek modern bands.

Clean the ring using warm water, mild soap, and a soft-bristled brush, ensuring it is checked periodically by a professional jeweller to confirm claw settings remain secure.
