Shell Pendant: 2.125" (54mm) x 7.5 " (190mm) approximately. I've never put this on, but I suspect it would roll back and forth somewhat, depending on one's physique.

Conus shell, (Monetaria) cowrie shells, clam shell heishi, conch shell (beads), dyed Lagrimas de Maria grass seed (blue), Pernambuco tree seed (red), glass and carnelian beads, waxed linen, and polished hemp cording. Inside the conus shell is a round clay fired spindle whorl of indeterminate age/origin.
