This is a pretty nifty deal. It's made of 12 or 14 gauge Sterling silver; it has extensive, quality hand-stamping on the Sterling; a tid-bit of repousse' on each side, and a nice rectangular piece of Sleeping Beauty turquoise topping it off. And, it's affordable! Weight is a nice three-ounces; width is 1 and 5/8th's-inches throughout, and it fits a person with a wrist circumference (including the "gap" in the cuff) of 6.75-inches (though since it has only a single stone, it can be adjusted a quarter-inch either way). Hallmarked "M." That is the same hallmark as Matthew Jack, son of Ray Jack, but there are likely other Navajo using a single M as a hallmark.
