This is a beautiful antique Edwardian bar pin in Sterling silver set with tiny pale green glass stones. It fastens with an older style safety catch and it is marked Sterling on the back though the stamp is rather faint.
It measures 2 1/2 inches long and is a little over 1/4 inch wide. It is in very good condition but it is missing three of the tiny stones. Because of the intricate design this is hard to notice.
