Green Gemstone Bead Necklace with Connecting Donut Pendant Set

Green Gemstone bead necklace with connecting donut pendant & Earring set. I believe the semi precious Gemstones are Chrysoprase. I might be mistaken but they are gemstones. The necklace has about 3/4th inch x 1/2 inch wide oval gemstone beads with silvertone decorative spacer beads. The center is a 1-3/4th inch round donut gemstone and connecting to necklace with silver glass beads. Necklace measures 19 inches long x a 2 inch drop in center. Good working silvertone floral toggle clasp. The matching pierced earrings dangle down to about 1 inch. They have silvertone leverbacks. No designer hallmarks. Very good condition. v.oo
