Bone jewelry is the only kind of bone I have to pick. These bone hoop earrings were carved by hand then cast in solid bronze and sterling silver. The end of each hoop is a post shape and completed with a hard rubber ear nut. 3-dimensional bone hoop earrings measure approximately 1.75 inches from top to bottom.
