Love these chic hoop earrings!  This pair were made in Mexico circa 1970 and each earring has three diamond shapes containing crushed inlaid turquoise on one side.  They measure 1.75" diameter and are stamped "HECHO EN MEXICO MCF" with an eagle hallmark denoting Taxco.  They are light and very flat, weighing just 5.6 grams each--perfect for swingy summer wearing!  They also have a nice patina, but could be polished up if the wearer prefers.
