Art Deco .50 Carat Transitional Cut Diamond Platinum Vintage Engagement Ring
Circa 1920

Art Deco vintage engagement ring centered with a .50 carat transitional cut diamond within a platinum setting with hand engraving and geometric designs that sits low to the finger for added comfort and practicality. Dating to the 1920s–1930s, the ring reflects the Art Deco fascination with geometry and symmetry, framing the center diamond within a rectangular platinum design accented by smaller diamonds and fine hand engraving. Open spaces between the diamond-set sections add another geometric element, while engraved details continue onto the shoulders. The transitional cut center diamond also places the ring at an interesting moment in diamond-cutting history, bridging the proportions of earlier Old European cuts with the greater symmetry of the emerging modern round brilliant. Designed to sit low to the finger, the setting keeps the diamond close to the hand, making this nearly century-old ring surprisingly practical for everyday wear.
