Art Deco 0.90 Ct Diamond Ring In 18 Karat White Gold

Art Deco 0.90 ct diamond ring in 18 karat white gold. Art Deco ring set with a 0.90-carat old European-cut diamond framed by a halo of eight single-cut (8/8) diamonds. The perimeter of the ring head is delicately highlighted with fine millegrain detailing. The shoulders are each set with an accent diamond on either side of the central motif. The central diamond exhibits what is known as the "kozibe effect": an internal multi-reflection reminiscent of a kaleidoscope. When viewed face-up, a ring of small reflected facets appears to dance inside the stone as it moves. Antique Art Deco ring, circa 1930-1940, France.
