Art Deco jewellery, prominent from 1920 to 1935, is characterised by geometric shapes, clean lines, and symmetrical structure. Rings from this era frequently feature stepped shoulders, baguette-cut side stones, and white metal settings such as platinum or white gold.

During the 1920s, jewellers predominantly used platinum and 18ct white gold to achieve a crisp, monochromatic finish. Central stones were typically framed by smaller accent diamonds, such as baguette or single cuts, set into structured mountings.

Authentic pieces usually feature geometric mount construction, period-appropriate diamond cuts such as old European or early brilliant cuts, and internal hallmarks indicating gold purity or maker marks consistent with early 20th-century craftsmanship.

An antique diamond solitaire pairs well with simple, unadorned white gold or platinum wedding bands. The clean geometric lines allow it to stack neatly alongside modern minimal bands or complement vintage-inspired jewellery ensembles.

Clean the ring using warm water, mild soap, and a soft-bristled brush to gently remove build-up around the claws and setting. Avoid harsh chemical cleaners and have the claw settings periodically checked by a professional jeweller to ensure stone security.
