Signed Dia Diodato sterling 925 pin pendant in a Modernist design. The piece is also marked with the Mexican eagle hallmark used prior to 1975. It measures 3 1/8" x 2 1/8" and weighs 29.7 grams. Diodato signed pieces are very rare. This would make a great addition to a serious Mexican silver jewelry collection. There is surface scratching as would be expected on a vintage piece, otherwise condition is good.
