Bruce Morgan's 14kt. gold and Sterling cuffs are the benchmark in this style of Navajo jewelry. He makes these in several gauge thicknesses, but the one pictured above is the thickest. It is exactly 1/8'inch thick—probably 10 gauge. We always go for the most substantial. The permanent wrist size circumference (including the "gap" in the cuff) is 7.25-inches. It will not bend due to the extraordinary thick gauge of the Sterling. Very, very thick. You can find thinner ones by Bruce on the internet, but few dealers will have the thick one. And they will likely charge the same amount for the thiner ones as this heavy-silver one is priced here. NOTE: We have one more of these that is virtually identical except for a slightly different design on the gold insert, AND, it is a permanent size of 7.50 (slightly larger wrist circumference that this one pictured here). Morgan inserts a 14kt. gold strip that is inlaid into the silver. We presume it is gold-fill—as solid 14kt gold as thick as this insert would make this piece extremely expensive. Gold-fill is fine, as it won't wear off like gold plate. Width is 1/8th-inches throughout. Weight is 123-grams, or 4.4-ounces. It is quite substantial. If you can't find a original 1967-Shelby GT with all numbers matching, this is the next-best thing. Hallmarked "B. MORGAN," along with "14kt." Complimentary Priority shipping within the U.S.
