This is a fantastic Eisenberg set. The brooch has all sizes of clear rhinestones. The metal is rhodium plated. The brooch is hallmarked “Eisenberg”. The earrings have no hallmarks but do match very well. The brooch measures 2 1/2″ X 2″. The earrings are 3/4″ clips. The pin alone weighs 54.4 grms. I would date this great set at c1950′s.
