Description

This is a most stunning “Art Deco” ring

This would make the most perfect ring for a lover of the Art Deco period. Someone who loves the design … without excessive flamboyance.

The ring is clearly marked for platinum, the central Natural Diamond measures a minimum of .33ct. The reason I state minimum is because the stone has not been removed from the mount to measure, and it is a deep stone.

The stepped shoulders are further embellished with baguette cut bright sapphires in total four graduated stones which catch the light and compliment the very bright , brilliant cut central diamond, which really radiates the light.

The whole settings are surrounded by millegrain effect.

This is a truly remarkable ring

At some point it has been resized and it now measures almost K

Date of Manufacture

Antoinettes Heirlooms has dated this Art Deco Diamond Ring to the 1930s.

FAQs

Art Deco jewellery, prominent from the 1920s to the 1930s, is characterised by geometric symmetry, clean lines, stylised motifs, and a strong emphasis on contrasting colours using platinum and gemstones like diamonds and sapphires.

Art Deco rings predominantly utilised platinum for its strength and bright white finish, which allowed for delicate settings without obscuring the stones, alongside calibre-cut sapphires, emeralds, rubies, and diamonds.

Authentic pieces often feature period-specific diamond cuts such as old European or transitional cuts, handcrafted millegrain detailing, platinum hallmarks, and construction techniques typical of the early 20th century rather than modern casting methods.

An antique ring can be worn as a striking standalone statement piece or paired with a simple contemporary wedding band to highlight its historical geometry and intricate craftsmanship.

Vintage jewellery should be cleaned gently using warm soapy water and a soft brush, avoiding harsh ultrasonic cleaners on softer gemstones, and stored individually in a lined box to prevent scratching.
