This vintage Art Deco ring originates from the 1930 period and takes the form of a three-stone diamond trilogy design. Fashioned from platinum, the piece presents a bright silver-coloured finish with a slender, tapering shank. The visual composition includes three round old European cut diamonds secured in traditional split claw mounts, complemented by delicate decorative metalwork along the gallery. The central diamond weighs approximately 0.66 carats, while the two flanking stones weigh around 0.41 carats each, producing a total approximate weight of 1.48 carats. Across the setting, the piece measures 30 cm high, 25 cm wide, and 5 cm deep. In a contemporary home, a ring of this type finds a place in a personal jewellery collection as an everyday or occasion accessory worn upon the hand. The silver-toned platinum band and brilliant-cut stones coordinate easily with various styles of modern apparel and other fine jewellery items. The piece serves as a traditional finger ornament suitable for personal adornment or gifting on significant occasions.

FAQs

A three stone ring, also known as a trilogy ring, features three gemstones positioned horizontally across the band, traditionally representing the past, present, and future of a relationship. Popularised throughout the Victorian, Edwardian, and Art Deco eras, these designs consistently highlight fine diamond settings.

Jewellery from the 1930s was predominantly crafted from platinum, white gold, or yellow gold with platinum head mounts. Diamonds from this period frequently feature hand-cut facets such as the old European cut, characterised by high crowns, small tables, and open culets.

Authentic old cut diamonds exhibit distinct hand-faceted proportions, including a deeper pavilion, rounder girdle shape, and a flat culet visible through the top table. Additionally, hallmark stamps inside the band indicating metal purity and period construction techniques assist in verifying age.

A vintage trilogy ring can be worn independently as a statement band or layered alongside a slender, plain precious metal wedding band. Its classic proportions allow it to coordinate effortlessly with modern fine jewellery and everyday wear.

Clean the ring using warm water, mild soap, and a soft-bristled brush to gently remove debris from underneath the claw settings. Routine checks by a professional jeweller ensure that the claws remain secure over extended wear.
