We ordered a loose 2.5 carat round stone and set it in a tiffany mounting and put it together with two diamond eternity bands. We couldn't be happier with how it turned out, even the owner of our local jewelry store didn't know is wasn't a diamond. When I told my jeweler it was a moissanite he said it was the best one he'd ever seen. My stone always tests positive as a diamond and I've never been questioned about it's authenticity. It's an amazingly beautiful stone and we will absolutely purchase more. The staff was wonderful and very helpful and always availble to answer my questions. If you're still undecided, take a chance on moissanite, you will not be disapointed.
