These are vintage clip earrings by DeLizza and Elster. They designed under the name Juliana among others, but never marked their pieces. One of Juliana's design hallmarks is the open back settings. These earrings have this hallmark design. They are in fantastic shape with almost no wear. The oval pair is made of Smokey and crystal rhinestones set is silvertone metal. They measure about 1x .75 inches. The blue pair has a great combo of blue, AB, and pink rhinestones set in silvertone metal. They are just over an inch across. Each pair sold separately.
