Art Deco style 1.51 carat GIA cushion cut diamond platinum engagement ring

This magnificent Art Deco–inspired engagement ring showcases the timeless romance of an Old Mine cut diamond wrapped in the structured elegance of platinum. At its center rests a 1.51-carat GIA-certified Old Mine cut diamond, glowing with refined H color and lively SI1 clarity. Its cushiony silhouette and antique-style faceting create a soft, enchanting brilliance that echoes the craftsmanship of early diamond cutting traditions, bringing warmth, depth, and character to the ring’s bold architectural form.

Encircling the centerpiece is a stunning arrangement of six baguette cut diamonds and twenty single cut diamonds, together weighing approximately 0.60 carats. Their crisp H–I color grades and VS–SI clarity enhance the center stone with a bright, harmonious sparkle. The baguettes contribute sharp Deco geometry, while the single cuts add a delicate, vintage flicker—two worlds of design coming together in perfect balance.

The platinum setting, substantial and expertly crafted, reinforces the Art Deco aesthetic with its symmetry, strong lines, and luxurious weight. Though created in the modern era, the ring carries unmistakable echoes of the 1920s, offering a blend of historical romance and contemporary sophistication. This piece is ideal for someone drawn to antique-inspired beauty, distinctive craftsmanship, and the enduring elegance of diamonds shaped by tradition.
