I bought it in August, and it was beautiful. Now, we just noticed that on the very top on the flat face, there is a crevice. A huge crevice that looks like a scratch. It has to be a new scratch. She's been showing it to everybody she knows, google-eyed over it since the summer and she would have obviously seen it. Now we notice this gigantic gouge out of it so we take it back to the store because we bought the warranty. The jewelry store's gemologist claims that it had to be there, it's not a scratch. It's physically impossible to scratch. All non-flawless diamonds have flaws, like crevices or inclusions. You can even take it to an independent gemologist and he'll tell you the same thing. I tell him "I won't take it to another gemologist, I'll take it to small claims court and a judge will read the details of your warranty and determine that you need to replace with a diamond of equal or better value" He changes his tune and offers for us to come into his shop where they have a microscope and we can check out a few different diamonds. He says "We can replace this diamond that has a crevice with one that has inclusion." How do I not get screwed? How do I know if they didn't fill the crevice with some kind of epoxy just to sell it, and now that it fell out, we're stuck?
