Its been about a year since I posted needing help with a bead ID, and hope that you can help.

Bought a necklace at a consignment store today, and this bead was the focal bead strung with several small coral beads. Have never seen a bead like this, and it looks really old. I'm sure its an agate of some kind. I plan to restring the necklace to wear, and would love any feedback on this bead. Thanks very much!
