The most common of crystal necklaces has round faceted beads. This necklace has beads with six sides around and three sides at each end. They are exquisite. The beads are graduated in size all along the necklace with the largest in the center front. Each bead is the same shape. Necklace is strung on chain and has a spring ring clasp. There are small goldtone spacers and crystal spacers along the necklace. It is 18 3/4" long. I can add a little vintage chain to each end to extend that length if you prefer it longer. The large center bead is about 15mm. Necklace is in excellent condition. I did not examine each bead with a loupe so there could be some very minor nicks. This would be consistent with its age and use.
