The listing, 925 Silver Chain has ended.
What you see is what you get. Beautiful and heavy, 1.96oz (557g), 19" long. I got this at an estate sale two years ago and don't know its history. The clasp is stamped 925, but the rings are not welded, so it could be silver plate with a silver lobster claw. If it is plated, it's a very heavy plate. I wore this daily for at least 6 months after I got it and there is no sign of anything but silver. Still, I can't guarantee it's not plated and I'm not going to go to the expense and trouble to have it authenticated, so bid accordingly.
