Original Art Deco jewels from the 1920s-30s that feature a demantoid garnet are exceedingly rare, and this genuine Jazz Age jewel is a fabulous example. A gemmy cushion-cut Russian Demantoid from the Ural Mountains, weighing .84 carat (accompanied by gemological report from the AGL), casts an exotic apple green color from within a striking mounting, hand fabricated in platinum, composed of fans of sparkling European-cut diamonds supported by a pierced geometric under gallery. A singular and stunning wearable collectable. 5/8 inch. Currently ring size 7 3/4.
