This 1920s Art Deco ring is fashioned from platinum with a silver colour finish, displaying a trilogy setting that holds three round brilliant cut clear diamonds in claw mounts alongside a plain band. The piece features a pierced under-gallery beneath the stones, polished prongs holding each round diamond securely, and individual settings that allow light to pass through the clear stones. The ring is set with three diamonds of approximately 0.28 carats each, producing a total carat weight of approximately 0.85 carats. The overall size is UK size S. The timeless geometry and sparkling stones suit use as an engagement ring worn alongside a wedding band or worn independently as a dress ring on any finger. Platinum construction provides durability while maintaining a bright silver tone that complements the clear brilliance of the faceted diamonds. The side-by-side trilogy arrangement creates a balanced profile across the hand. Certified through prior appraisal, the piece brings period character to contemporary collections.

FAQs

An Art Deco trilogy ring is a piece of fine jewellery created between 1920 and 1939, featuring three side-by-side gemstones, typically diamonds, representing the past, present, and future. The era is characterised by geometric symmetry, clean lines, and the widespread use of platinum settings.

Art Deco trilogy rings are predominantly crafted from platinum or white gold, chosen for structural strength and neutral white tone. These settings typically hold diamonds cut in traditional styles, secured by claw or bezel mountings.

Authentic Art Deco pieces often feature platinum hallmarks, geometric setting details, and hand-cut diamonds such as Old European or transitional cuts. The craftsmanship frequently displays subtle openwork or pierced under-galleries beneath the mountings.

An antique diamond trilogy ring can be worn as an engagement ring, paired with a plain platinum or white gold wedding band. It also serves as a standalone dress ring suitable for daily wear or formal occasions.

Clean the ring using warm water, mild dish soap, and a soft-bristled brush to remove oil and debris around the settings. Inspect the claws annually with a professional jeweller to ensure the gemstones remain securely mounted.
