Vintage mid century rhinestone pin and earring set

This beautiful set consists of a pin and a pair of screwback earrings. It is set in gold tone metal and made with multicolored pastel rhinestones and fake pearls. the earrings also have pear shaped faux opals. The pin is 1 1/2'' across and the earrings are 1'' across. There are no markings but they came in a box labeled Shields Fifth Ave. I don't know if they originated in that box or were stored there later.
