Very nice condition. The gold marks on the post are worn but the metal was professionally tested and is solid 14K gold. The natural diamond in the eye of the Jayhawk measures approximately 1mm across. Pin measures 1/2" x 1/2". Weighs 2.24 grams. Appears to be a custom made piece. Will function as a tie tack or lapel pin. Lovely vintage pin. Please feel free to ask any questions.
