This black and white beaded necklace is a lovely take on this color combination. What appear as white glass beads are actually clear glass with white swirls. The variation in shape and size of beads adds to the beauty of this substantial piece. The beads and black spacers are strung on chain. This jewel closes with a barrel clasp marked "Made in France". All of these features identify this stunning jewel as made by Louis Rousselet. It has been authenticated. Once part of my personal collection, this gorgeous necklace is always a classic.
