This shamrock pin has a sharply defined swirl pattern etched into it and a silvertone center. The etching is done so well that it gives the appearance of being enameled. The pin measures about 1-5/8" x 1-7/8" and though it does have some age-related scratches (quite fine--more of a patina) it is otherwise in excellent vintage condition. It is marked on the back "W. Germany." Be great to wear on St. Pats day or go give to an Irish friend!
