Gorgeous strand of 10 lava beads, dyed black, in a pleasant lentil/donut shape with a center hole. The beads measure 32-33mm in diameter and are 9mm thick in the middle of the bead. (Like all lentil beads, these are thicker in the center.) The center has a drilled hole that is approximately 2mm in diameter. You will get a strand of 10 beads, as shown.
