These 6mm round black tourmaline gemstone beads are wonderfully shaped, drilled, and polished. The beads are very close in size to one another. I'm very happy with this batch.

Black tourmaline is called schorl. It has a Mohs hardness rating of 7 to 7.5 and offers the jewelry designer an affordable, naturally black gemstone bead.
