Vintage large black bone colored resin metal studded buckle bracelet.  I'm calling 1940's on this very unusual bracelet.  You know it's antiquated, but it's also so contemporary looking. I do not know what this bracelet is made out of. For awhile, I thought horn or bone. There are some chips in the black glaze, mainly on the inside near the clasp stud. The rest of the studs are inlaid. This piece would best fit a woman's medium to small wrist.
