This bracelet is Edwardian in period and over 100 years old. It is a classic Heart Lock clasp in 15 C gold hallmarked London 1908. It is attached to a 9 C gold curb link bracelet with scrolling spacers and grooved bar highlights. It is 7/16" wide and weighs 19 grams.
It is in excellent estate condition and I love that the English hallmark each and every link for fineness. And it has a safety chain for security.
