We used to call this "Turritella" until a customer told us we were wrong. (Thank you!) "Sea Lilies" are actually animals called crinoids. Crinoids were very abundant during the Paleozoic era. And now we can make beads out of their fossilized remains. It's a pretty rock once you look closely. Temporarily strung (no clasps). There are about 65 beads on a 6mm strand.
