This glasses lanyard/chain is made up of gemstones and glass beads. The gemstones in this lanyard/chain are 8mm crystal faceted drop beads in marbled mint, 3mm amazonite faceted round beads, 8mm amazonite round beads, 10mm matte carnelian. Also there are a mixture of clear, white and translucent amber glass beads with some ornate metal lantern spacer beads in antique bronze throughout the piece. The length of the silver-plated chain section of the eye glasses lanyard/chain is 21 inches long, both the beaded sections are 10 inches long so you get a lot of beautiful gemstones, glass and metal beads. In total the length of this piece is 41 and 3/4 inches long which is 5 inches longer than industry standard. But it is still comfortable to wear though, due to having the length of chain at the back of the neck.
