the woman I got it from didn't seem to be lying, and while im not an expert, I do have a bit of knowledge on them, and there is no indication that this is a fake, no color reflection, breatheable setting, and no fog on it. the more I say about it the more I want to keep it!
The lady I bought it from, It came with like 17 silver chains, plus a few diamond earrings that had no match. I sold most of the other stuff on eBay, so there's that I guess.
