This vintage tie tack or lapel pin has a cursive "G" in black enamel on the front. The back is marked "STERLING" and a makers hallmark which has a big "A" in what looks like a circle though part of that circle is either worn off or unstamped. The clasp part is not stamped so most likely is not sterling. The pin is app. .60inches x .35inches. There is no enamel damage and very minimal wear to the sterling. The piece is not tarnish - just the poor lighting makes it look shadowed in spots.
