This fun vintage (1940s) sterling heart charm features a shamrock with a scroll border. The heart charm measures 11/16ths of an inch by 9/16ths of an inch. The back is marked sterling and has been nicely engraved with the name "Martha". This heart charm could stand a good cleaning. I will leave that decision to the new owner. Condition is very good with light surface wear. This is guaranteed to be a period charm and is not a reproduction.
