1920s Platinum 1.10ct Old Mine Cut Diamond Engagement Ring | Timeless Art Deco Elegance

$4,995.00

This elegant 1920s platinum engagement ring features a dazzling 1.10ct old mine cut diamond, celebrated for its soft, candlelit sparkle and romantic, hand-cut charm. Framed by delicate .10ct side diamonds, the setting captures the refined artistry of the Art Deco era — a time when jewelry reflected bold innovation and modern beauty.

Handcrafted in solid platinum, the ring’s clean lines and timeless silhouette speak to a period when life was changing rapidly: jazz filled the air, women embraced newfound independence, and design broke away from tradition. The old mine cut, with its larger facets and gentle glow, offers a look unlike any modern cut — each diamond uniquely shaped by hand over a century ago.

This is a ring that carries both history and heart — a perfect choice for someone who treasures elegance with a story.
