Blue square stone earrings. These beads are sewn on to a metal top by what looks like metal wire or a strong plastic wire. They are clip on earrings so they will be perfect for those without pierced ears, or those with sensitive ears. The back is just a gold toned metal. There are no markings for brand name or type of metal. The diameter of the earrings is around 7/8". These are quality fashion earrings from the mid 1950's.
