FAQs

Trilogy rings feature three central stones traditionally representing the past, present, and future of a relationship. During the Art Deco era of the 1920s and 1930s, jewellers combined clean geometric lines with contrasting gemstones, frequently pairing sapphires with diamonds in mixed-metal settings.

Art Deco trilogy rings were predominantly crafted using platinum or a combination of platinum settings with eighteen-carat gold bands. Platinum allowed goldsmiths to create strong, delicate claw mountings that held precious gemstones such as diamonds, sapphires, and rubies securely.

Authentic Art Deco rings typically feature hand-cut gemstones, such as cushion or transitional cuts, along with mixed metal settings combining platinum heads and yellow gold shanks. Hallmarks inside the band often indicate metal purity, maker marks, and assay marks corresponding to the period.

A classic Art Deco trilogy ring functions as a standalone statement piece or as an engagement ring paired with a slim platinum or yellow gold wedding band. Its neutral tones and geometric design complement both formal attire and modern minimalist wardrobes.

Clean the ring gently using warm water, mild soap, and a soft-bristled brush to remove dust from behind the stones. Avoid exposing platinum and gold settings to harsh household chemicals, and store the piece individually in a lined box to prevent scratching.
