N/A Vintage Goldtone Chain Necklace

Vintage goldtone chain necklace with tiny rhinestones, or diamonettes? I'm not sure what they are but it's really pretty. This necklace is goldtone but also has some silvertone on it too which I'm. ot sure if its due to the gold layer rubbing off or if it was made this way. But to me it looks like it's supposed to be this way and is really pretty like this.
