Vintage 3 strand Herringbone Chain Gold Over Sterling Silver 925 Designer JCM Adjustable Necklace or ChoKer Cocktail / Casual

This is a gorgeous gold over sterling silver three strand herringbone style Necklace. The necklace at full length is approximately 17.75 inches long but can be adjusted down several inches to be approximately 13 inches as a choker.
Made by JCM And stamped Italy 925. There is one small wear mark on one side (it is reversible) Hardly worth noting but I like to give full disclosure, please see photo one side has a mild crimp and on the other side is slight wearing of the gold but neither one are generally noticeable.
