Art Deco platinum ring with a 1.04-carat oval diamond, circa 1930
The central oval diamond, with its pleasing soft yellow colour, brings gentle warmth to a stepped platinum frame. Dating from around 1930, this Art Deco ring balances architectural precision with the delicacy of fine millegrain edges. Its old-cut diamonds give the composition a distinctive character, while their traditional association with enduring love lends a personal meaning to a ring firmly rooted in its own time.
