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 them. It's a pretty rock once you look closely. Temporarily strung (no clasp). There are about 45 beads on an 8mm strand.
