I have short necklace made of 6 gray cords. It has 7 heavy silver tone rings or beads. They alternate between smooth and patterned. It has a great clasp that looks like a heart shaped lock. It is 17 1/4 inches long. I don’t see any maker’s marks or metal content markings so I don’t know what the metal is. See my other ads for jewelry, artwork, home decor and more.
