I have a gorgeous 3 carat wedding ring with round stones. I wanted a ring that was a different style that I could wear instead every once in a while. This ring sparkles and is very pretty, however if I put my real ring on at the same time with this one, there is no comparison. But having this one on by itself, it can pass for the real thing- if that makes sense. Also in natural  lighting this one doesn't have that much sparkle its under florescent light where it  sparkles and looks the best, my real one sparkles no matter where it is.  My real one is a 6k ring and this one is less than a 100 bucks- so I would hope there would be a difference - lol  but for the money and to just have something different to wear ever once in a while you cant beat it.  I will be buying more styles from this company.
