The metal has a polished finish and the central sapphire shows multifaceted faceting. The head of the ring measures 1.28 cm by 1.12 cm, with the sapphire measuring 0.83 cm by 0.67 cm, and the mount sitting 0.42 cm from the finger.

FAQs

Produced predominantly between 1920 and 1939, Art Deco rings combine geometric precision with vibrant gemstones, frequently placing deep blue sapphires alongside brilliant diamonds in platinum or white gold settings.

Rings from this period commonly feature platinum or high-karat white gold mounts, set with natural sapphires surrounded by round brilliant or old European cut accent diamonds.

Authentic period pieces typically show hand-crafted gallery details, era-appropriate hallmarks, milgrain edging, and gemstone cuts characteristic of early twentieth-century lapidaries.

A vintage sapphire ring functions as a standalone statement piece for formal occasions or as an elegant daily engagement ring paired with modern platinum bands.

Clean gently using lukewarm water, mild detergent, and a soft-bristled brush, avoiding harsh chemicals, ultrasonic cleaners, or extreme temperature fluctuations.
