This 1930s Art Deco engagement ring in platinum features two old brilliant-cut diamonds (approx. 0.36ct total), framed by 22 lively single cuts (approx. 0.60ct), all graded F–I, VS–SI. The design, with its geometric layout and fine millegrain borders, balances structure with elegance. Viewed from any angle, the stepped octagonal settings and subtle elevation offer a quiet interplay of light and symmetry—classic Deco with an enduring sense of romance.
