Hammered Silver-type Necklace

I bought this necklace for the stellar look - planets in orbit, perhaps? Three strands. No markings. It hangs about 8" from top when catch is hooked in the middle. Made of some type of metal - certainly not silver, but silver-y in looks. I love it, but never wear it. I am home-bound. Who needs jewelry when you don't go out!?!
