Art Deco Natural Blue Sapphire and Diamond Ring with EGL Certification

This exquisite Art Deco era ring (circa 1920–1930) showcases a natural cushion-cut sapphire of 2.9 carats, glowing in a delicate light blue hue. The sapphire is certified by EGL as untreated, underscoring its rarity and authenticity. Surrounding the center stone are 26 single-cut diamonds (G–H color, SI1–SI3 clarity) with a combined weight of approximately 0.55 carats, their sparkle accentuating the cool brilliance of the sapphire.

The platinum mounting exemplifies the precision and elegance of Deco design, balancing geometric form with refined craftsmanship. The face of the ring measures 0.6 inches by 0.75 inches across, creating a striking yet sophisticated presence on the hand.

Currently a size 8.25, the ring is in great condition and may be resized upon request for an additional charge. A jewel of both historical and gemological importance, this ring embodies the enduring beauty and artistry of the Art Deco era.
