This is a gorgeous Art Deco rock crystal Pools of Light pendant on a sterling silver chain. The orb reflects a "pool of light" around the pendant and objects viewed through the crystal appear upside down. The rock crystal orb is held in place by three silver bands that meet at the base of the pendant and it has a diameter of 7/8". The chain is 18" long and is marked "sterling" on the clasp. Condition of the necklace and pendant is excellent.
