1920s Platinum Old Mine Cut Diamond Engagement Ring
An exceptional Art Deco engagement ring dating to the 1920s, crafted in solid platinum and set with a beautifully proportioned 1.10 carat old mine cut diamond. Hand-cut over a century ago, the diamond displays the broad facets and soft, luminous glow that define antique stones — a character impossible to recreate in modern cuts.
The center diamond is framed by a refined arrangement of accent diamonds totaling approximately 0.10 carats, adding subtle brilliance while preserving the ring’s original balance and architectural clarity. The platinum setting reflects the precision and restraint of true Art Deco design, created during a period when craftsmanship and materials were paramount.
Old mine cut diamonds of this size are increasingly scarce, particularly when preserved in original platinum mountings. This ring remains in excellent antique condition and has been carefully selected for its authenticity, proportion, and enduring elegance.
Equally suited for a collector or as a once-in-a-lifetime engagement ring, this piece represents a rare opportunity to own a genuine example of early twentieth-century fine jewelry.
