Art Deco Emerald & Old Mine-Cut Diamond Ring

Dating to circa 1920, this platinum Art Deco ring features an oval mixed-cut emerald framed by four precisely fitted triangular French-cut emeralds, weighing 1.18 total carats. Together, the five emeralds create the appearance of a larger geometric emerald centerpiece, with the triangular cuts filling the corners and transforming the oval into an architectural composition.

Flanking the emerald are two substantial old mine-cut natural diamonds totaling 2.28 carats, graded VS2-SI1 clarity and I-J color. Fine milgrain outlines the geometric panels, while pierced work and hand-engraved floral and wheat motifs extend along the shoulders and side surfaces. 

This ring illustrates a great strength of Art Deco jewelry: gemstones become architecture. At the same time, the jeweler didn't abandon earlier traditions. Antique old mine-cut diamonds sit beside sharply organized Deco geometry, while floral and wheat engraving softens the platinum framework. The ring is approximately a size 7.25.
