These are very unusual tourmaline beads. They are like flat teardrops, drilled at the top but more of a freeform style. The beads have a high polish. The tourmaline is mainly dark and light pink and shades of green. There are a few blue and a few bi-color tourmalines mixed in. The beads average 10mm-14mm long and 6mm-9mm wide. The necklace is 19-1/2" long with a lobster claw clasp. Because of the unusual bead shape the necklace lays really pretty on the neck.
