Unique Stone/Crystal/Bead Adjustable Necklace - Vintage

I have had this beautiful piece for quite a few years. I purchased this at Macy’s in New York in 2000. It is solid and well made. The genuine stones (don’t remember what kind) crystal rings and frosted pewter toned beads-which are sturdy and do not chip-are strung on wire, not elastic. Secure lobster claw clasp. *Please note beads are not real pewter, they are pewter colored. This piece is adjustable from 18 1/2-22 1/2. It weighs 4 oz. I snapped pics of various backgrounds to better showcase the item.
