French GIA 1.50 carat old mine cut diamond platinum engagement ring

This enchanting French mid-century engagement ring centers a beautifully preserved 1.50-carat GIA-certified Old Mine cut diamond, glowing with the romantic warmth of its U–V color grade and the lively brilliance that only antique faceting can offer. The diamond’s pillowy shape, broad facets, and soft sparkle evoke the craftsmanship of the 19th century, while its SI1 clarity allows light to move gracefully throughout the stone, giving it a luminous and expressive character.

Framing the center diamond are six delicate single cut diamonds, together totaling approximately 0.06 carat. Their bright G color adds gentle contrast, while their older-style faceting provides a subtle flicker of light that enhances the center stone’s glowing presence without overshadowing its antique charm.

The ring is crafted in platinum and bears the French dog hallmark, affirming its Parisian origin and adding a touch of authentic heritage. The sleek mid-century design emphasizes clean lines, balanced proportions, and understated elegance, allowing the Old Mine cut diamond to remain the undeniable focal point.

Rich in history, French craftsmanship, and timeless beauty, this piece is ideal for anyone who cherishes antique diamonds and desires a ring that feels both soulful and sophisticated—an exquisite blend of mid-century refinement and old-world romance.
