Art Deco Marquise Diamond and Sapphire Engagement Ring
A true Art Deco treasure, this beautifully balanced engagement ring captures the elegance and geometric harmony of the era. At its center is a genuine antique marquise brilliant–cut diamond measuring approximately 8.60 × 5.10 × 3.05 mm, estimated at 0.80 carat, with I–J color and VS2–SI1 clarity. The elongated silhouette creates a graceful presence on the hand. The small open culet showcases the unmistakable charm of an antique cut diamond.
Flanking the center stone are two natural half-moon blue sapphires totaling approximately 0.10 carat, complemented by four custom-cut rectangular synthetic blue sapphires totaling approximately 0.12 carat. Twenty natural diamond accents add an additional 0.40 carat of sparkle, enhancing the ring’s symmetry and brilliance.
Crafted in Platinum, this ring weighs approximately 3.00 dwt. The interior marking is present but no longer legible. Currently a size 6.75, the ring can be resized.
This refined and distinctive Art Deco engagement ring is ideal for someone seeking a truly one-of-a-kind piece, exceptional craftsmanship, and enduring beauty. Authentic Art Deco rings of this caliber are always coveted and rarely available for long.
