This is a lovely piece. It appears to be a Victorian (circa 1850) copy of the Georgian French Heart. This one is crafted of French silver (sterling, unmarked, but tested) and glorious French paste. The piece measures 3 inches North to South, and 1 and 1/2 inches East to West.It weighs 26.11 grams. This would certainly dress up any outfit!
