Good condition with light wear. Beautifully constructed and hallmarked "925" on back of pendant, circular ring and clasp. Stones were tested with the Presidium Gem Tester II. I couldn't determine if they are iolite or tourmaline since both are in the same line on the tester. Mother of pearl is on the pendant. The circular ring does have a hinge on back so the chain can be changed. Measures 18" long with a 3" extension. No missing stones. Rather heavy. GORGEOUS PIECE OF JEWELRY!! ITEM#1628
