This is a silver tone choker necklace with grey glass moonstones and gold tone highlights. The necklace is not signed and I do not know who made it but the style reminds me a little of Brighton. The choker is adjustable and measures from 16 to 18 inches long. It is in very good condition and appears to have been gently worn, if at all. Please let me know if you have any questions. Thanks for stopping by.
