FAQs

An Art Deco crossover ring, also known as a bypass or moi et toi ring, features a band where two main central stones wrap around to meet, symbolising the union of two people. Emerging prominently in the 1920s and 1930s, these designs highlight geometric symmetry combined with fluid metallic curves.

Art Deco crossover rings are most commonly crafted from platinum or white gold to produce a sleek, bright finish. Settings typically incorporate precious gemstones such as diamonds, emeralds, sapphires, or rubies, often framed by smaller single-cut or rose-cut accent diamonds.

Authentic pieces from the era feature hand-carved milgrain borders, crown or collet claw settings, and platinum mountings stamped with period hallmarks. The gemstones often exhibit historic cuts, such as old European or transitional cuts for diamonds and classic round cabochon or faceted cuts for coloured stones.

The distinct geometric structure of an Art Deco crossover ring allows it to serve as a standout statement piece alongside minimal modern tailoring. It pairs equally well as an alternative engagement ring or stacked thoughtfully with fine band rings.

Emeralds are sensitive to heat and harsh chemicals, so clean them gently using lukewarm water, mild soap, and a soft brush rather than ultrasonic cleaners. Store the piece in a lined jewellery pouch to prevent the platinum and harder diamonds from scratching delicate coloured gemstones.
