From the very early Art Deco period, circa 1910, comes this exquisite and rare creation. Four matched, high crowned, French cut diamonds are arranged in a square forming the outside dimensions of a one and a half to two carat square diamond. The center diamonds are flanked by two attenuated triangles composed of calibre cut emeralds outlined with tiny antique cushion cut diamonds. The hand engraving on the sides and complete shank are as nice as we've ever seen. A true gem.
