Onyx and agate sterling Navajo stacker cuff

Lovely onyx and white banded agate stacker cuff - unfortunately a bit too small for me. The channel inlay goes around the entire length of the bracelet. It’s 5 3/8 inches inside plus a 1 inch gap for a total of 6 3/8 inches. It’s 3/8 inches tall at the widest point, tapering down to about 3/16 inches at the opening. It cannot be adjusted. Marked W and sterling. It was attributed to Wayne Etsitty.
