Sea bamboo coral is a substitute for coral used by today's jewelers because coral is an animal and illegal. These smooth round beads are 7mm wide with a horn of good luck in the center with 2 facing bead caps. There is a sterling silver handmade bead on the back of the bracelet as well. The horn is solid silver with red enamel and a rhodium finish. Bracelet is elastic and fits small to medium wrist, not large.
