Heavy silver Navajo five-stone cuff with White Buffalo stones, by Gilbert Tom.

This 6.5-inch total wrist circumference (including the "gap") cuff is classic Gilbert Tom, with his trademark scalloped edges and extensive hand-stamping.  His silversmithing has a distinct look—and feel—that bespeaks quality.  It's 12-gauge Sterling so I won't adjust much, maybe a eighth-inch either way.  The five white buffalo stones are outstanding, with a lot of iron-ore matrix which gives them character.   Width is an inch and five-eighths throughout.  We're waiting on a new scale, but best guess is about 4.5-ounces in weight.  Hallmarked "Gilbert Tom."
