This necklace has a very transparent feel, with a circular cut. I was told the material was crystal, but since there is no certificate of authenticity, I've listed it as "crystal-like." It might be crystal. Please understand that I cannot confirm this with certainty. It has been stored at home. I'm offering it for sale, hoping someone will use it. Thank you. Length: Approximately 40cm Largest crystal bead: Approximately 1cm
