I have a long silver tone necklace with 4 hammered metal open squares. 2 are silver tone and 2 are gold tone. I don’t see any maker marks or metal markings so I don’t know what the metals are. The chain is 32 inches long and the squares hang down just over 4 inches. There is no clasp. You just put it over your head. See my other ads for jewelry, artwork, home decor and more.
