A Lavender Tube Beaded Necklace Vintage Costume Jewelry Unique Handmade

This necklace is an enigma. I can't figure out what these beads are made of, I have never felt anything like them. They have some texture so my best guess is a dyed wood. The beads are very pretty and each one has a bit of a different pattern. It is an older piece and possibly handmade. The beads are each 3/4" long with silver tone rondel spaces in between each and a shepherd's hook clasp. It is in very nice pre-owned condition and is a unique piece. It is approximately 28" long.
