Blue-gray seed bead necklace with pearl accent

Blue-gray seed bead necklace with pearl accent (ring-shaped part) Blue beads are glass, gray are probably plastic that imitates some sort of colored wood or something like that. A pearl ring looks natural, I guess it is natural but not sure for 100%, so I list it priced as plastic. Necklace is preowned, in good/acceptable condition, has minor wear of use. Unbranded. Probably handmade (not by me definitely) Length is about 17 inches around neck. Diameter of ring-shaped accent part is about 2 1/3 inches.
