Beautiful Vintage Orange Agate Beaded Necklace and Earring Set

Beautiful vintage orange agate beaded necklace and earring set. The earrings and necklace both have large round polished agate beads, metal copper spacers, and amber colored faceted glass beads strung on wire. The necklace is finished with a dark copper square toggle clasp. The necklace is 21"in total length, and the earrings are slightly over 2" long. Each stone bead is approximately 1/2". Both the necklace and earrings are on the heavier side. Unmarked The set is in overall great condition. There are no chips or cracks in any of the stone beads. The copper beads do show tarnish and wear. I haven't tried to clean this set and could use a good clean to brighten it up.
