Art Deco GIA 2.17 carat old marquise cut diamond platinum engagement ring

This striking Art Deco engagement ring is a rare and captivating expression of 1930s design, defined by bold geometry, refined symmetry, and unmistakable vintage glamour. At its center rests a beautiful 2.17-carat old marquise cut diamond, certified by GIA and prized for its elongated silhouette and antique faceting. The marquise shape creates a dramatic, finger-lengthening effect, while the old cut facets offer a softer, romantic brilliance that feels luminous and full of character.

Framing the center stone are six old marquise cut accent diamonds totaling approximately 0.30 carats. Their mirrored shapes echo the central diamond, creating a cohesive and architecturally balanced design that is quintessentially Art Deco. The contrast between the H color center diamond and the brighter G color accents adds depth and visual interest, while the VS–SI clarity of the side stones ensures crisp sparkle and refinement.

Crafted entirely in platinum, the ring has a delicate yet enduring presence, enhanced by subtle engraved details that speak to the meticulous craftsmanship of the era. The cool-toned metal provides a perfect backdrop for the diamonds, emphasizing their brilliance while maintaining the clean, streamlined aesthetic for which Art Deco jewelry is celebrated.

Elegant, distinctive, and rich in period character, this ring is an exceptional choice for collectors and romantics drawn to rare diamond cuts, authentic Deco design, and engagement rings that tell a story of timeless sophistication.
