Ross-Simons 925 Sterling silver, turquoise and cultured pearl necklace NWOT

This is a beautiful necklace in excellent condition, never worn. Pearls have beautiful luster and turquoise nuggets have beautiful color and dark veins throughout, I tried to take pictures of both sides. Silver beads and chain have beautiful shine. Received it as a gift some years ago and its not my style but may be yours. It is 15" long with 3" extender.
