This is a silver tone mesh choker necklace with a two tone slide. The slide has a faux carved mother of pearl flower in the center. I cannot tell if the flower is made of stone or glass. There are no marks on the necklace and I do not know who made it. The necklace measures 17 inches long. The slide is 1-1/8 inches long. The necklace has a magnetic clasp. The necklace is in very good condition and appears to have been gently worn. Please let me know if you have any questions. Thanks for stopping by.
