I just received this ring today.  It is BEAUTIFUL!  I ordered it because the diamond fell out of my wedding ring, and the warranty is no longer valid.  My only problem is that it's just too much "ring" for my taste.  I've looked up comparable diamond rings and they run around $30k.  Nobody would ever believe that I was wearing a 30 thousand dollar ring so I've decided to return it.
I gave it 5 stars because of how it looks, even though it isn't the right ring for me.  The stones are VERY clear and they would look real on the right person.  I didn't realize it was 5 ct. until after I ordered it.  I'm still going to order a CZ ring, but it will be a much smaller one.
