This is a beautiful vintage nugget style 14K bracelet. It is marked 14K on one end and the "PAT 3308517" on the other end. This patent number is from March 14, 1967 and is for the type of clasp used on the bracelet. The length is 7 1/2 inches long and it is 1/4 inch wide. It is also 1/8 inch thick. The links are heavy and the clasp works well as does the safety snap. My postal scale is not vey sensitive but this appears to weigh 15 grams or .4 ounces. This is gorgeous on.
