This wonderful and very hard to find vintage (circa 1940s) sterling heart charm is one of the flower of month series (July) and was made by Walter Lampl. Water lilies are featured on the front of the heart and the back is marked sterling and "WL" for Walter Lampl. The heart charm measures 11/16ths of an inch by 9/16ths of an inch and has not been engraved. Condition is very good. This is guaranteed to be a period charm and is not a reproduction.
