It's a heavy necklace made from 4 individual strands of ball chain, and it has a snap lock closure at the back. Two of the chains are gold tone, and two of them are silver tone. This is an older, well loved piece, so there are some signs of that including wear through the finish on the back of the necklace, most notably wear through the gold tone plating revealing silver tone underneath. There is also some oxidation residue on the clasp and back of the chain. See photos.
