silver tone chain necklace with blue stone chips

Pretty large-link chain necklace in a silver-toned metal. Has a strand of turquoise-colored stone chips woven through the chain with a larger stone bead on each end, and a cluster of stone chips and silver faceted beads at one end. I don't think the stones are real turquoise, likely some less valuable stone. No markings to indicate brand or metal content. Silver beads show wear. Lobster clasp. 28", could be worn at a shorter length.
