Diamond Jewelry United review: engagement ring

I bought an engagement ring from these people a couple of years ago. I never liked the color and it sure wasn't an si3 stone. It's terrible. I didn't think much more of it until we were going to upgrade and it wouldn't test on a diamond tester. It's a real diamond, but it was messed with so much that it won't even test. It was testing as moissanite, but the jeweler agrees with the heavy inclusions and terrible color that it was indeed a diamond. This was really embarrassing for me with my wife because I'd never buy something of this quality on purpose. Don't buy from this place ever. I'm in the US and they are in Europe, so pretty much nothing I can do about this. I also think having the ring sized may have messed the "enhancement" up as well. Horrible. I left a good feedback on eBay under csfischer20 because I didn't know any better. This is a scam.
