Green Mother Of Pearl/Resin Pendant & Beaded Necklace w Matching Pierced Earring. I am actually unsure what the pendant is made of. I think maybe mother of pearl (MOP), or some type of resin or maybe even glass. There is a hand-painted gold design on the pendant. There are also glass/stone? beads present on the necklace and also the earrings. Necklace measures approx 20" with a 2 1/2" extender. Earrings are 1 1/2" long.
