Unsigned Silver Tone Vintage Oval Chain-Link Choker Necklace Earring Set

I have no real information about this set other than describing what you see here. I got this at an estate sale, I don't know who makes it. I didn't see any brand markings on it. It looks vintage, and looks like it would benefit from a good cleaning. It feels like metal, though what kind of metal I do not know. it is on the weightier side. Feels like a good quality piece when you hold it in your hands. Take a good look at the photos to see some aging and discoloration marks. It is a beautiful and very unique set. The color is silver, however, in some lights, it takes on a hint of gold. These pieces are very mysterious.
