This great looking bracelet is vintage circa 1940s or 1950s. It is fashioned from handcrafted sterling silver and I was told that the hallmarks indicate that it is Swedish in origin. The length is 7 1/4 inches and it measures 1 inch wide. It is stamped JSM with three crowns after that. It is also stamped U8 and has what looks like a heart with a crown inside of it and another 8 inside of a diamond like box. It weighs 53 grams and the condition is very good.
