"Knockout" is not a style, it is a little-used descriptive term. And this is, indeed, a knockout. It has five beautifully expensive Kingman Mine (Arizona) turquoise stones; thick 12-gauge Sterling silver; "old-style" patina Sterling; a few pieces of repousse' silverwork, and it is made by master Navajo Silversmith Gilbert Tom. You can see Mr. Tom at work in a video on the High Plains Jewelry Facebook page. Here he started with inch-and-a-half Sterling, and used a 1.25-inch-long stone as a centerpiece. To wear it one's wrist circumference should be 6.75-inches—which is a medium-large woman's or a small man's size. It weighs nearly five ounces (4.84-ounces) and is hallmarked "Gilbert Tom."
