Nice start to collecting and combining jewelry with sports. All of these pieces have silver toned backings and come with silver- hypo allergenic ear wires. The first is the Florida “Gators” measuring 3/4″ L X 1/2″ W. Next is the Chicago Blackhawks measuring 1″ in diameter. Next is the Seattle Seahawks measuring 1″ L X 5/8″ W. And finally is the Chicago Bears and they also measure 1″ L X 5/8″ W. Nice variety and all are in great condition. Well taken care of.
