Available is a Pair of 2 Vintage Brass Bone & Shell Bangle Bracelets, Tribal/Boho. The inside circumference of both bangles is 8.17 inches. The wide bangle is is nearly an inch wide. The narrower measures 3/8 inch. My guess is the wider bangle is inset with strips of bone and the narrower bangle is inlaid with shell pieces. Both bracelets have been dyed orange.
