This lovely necklace will sparkle and glitter in just about any amount of light. It is perfect to transition from day to evening. The metal is sterling silver with gold plating (gold vermeil). I am not sure what the stones are. They could be CZ's or glass or clear stones with an aurora borealis coating. They are set into this necklace like gemstones with the open back and no foil. Necklace is 17 1/8" long and weighs about 40 grams. The stones are about 7.5mm end to end. Necklace has a secure push-in clasp and two safety bars, one on each side of the clasp. It is in excellent condition.
