This necklace has the most beautiful square purple marbled glass pieces; I absolutely LOVE it. It measures 16" long and each section of purple glass measures 3/4" x 3/4". The are prong-set in a silver-tone (more towards pewter) colored metal. The are separated by a beautifully ornate link. There are small chips on the corner of a couple of pieces, but not noticeable (worth mentioning). The clasp is present and operates well. This vintage piece is in very good condition.
