This is a cuff bracelet that appears to be Native American. I cannot find any markings on it. The bracelet looks to be silver plated but it is not marked and has not been tested. The bracelet has an inlaid picture of a bird in the front. The bird is inlaid into either horn or faux ivory. The sides of the bracelet appear to be black onyx and some type of fossilized rock. The bracelet measures 7-1/4 inches along the outside from cuff end to cuff end. The opening measures 1-1/8 inches. The bracelet measures 1-1/2 inches wide. It weighs 90.0 grams. There is a line or crack in the faux ivory next to the circle with the bird. Otherwise, the bracelet is in good condition. It may need additional cleaning or polishing. Please let me know if you have any questions. Thanks for stopping by.
