Why is a lab grown diamond an upgrade over moissanite?

Whether it's an upgrade or not is up to whoever is purchasing it. There are some really nice moissanite jewels. In fact you can get like some pretty perfect looking moissanite pieces. But diamonds are the hardest things known to man. They're pure carbon. Moissanite's under light will have some purplish sparkle almost like a rainbow effect, whereas a diamond will have a fiery type of sparkle. Also when you look directly through it it's clearer from one side to the other. I'm not a diamond expert or anything like that I'm just a guy that bought a lab grown diamond for his wife and she absolutely loves it. But like I said she loved the moissanite I got her too, but it's because I gave it to her. And she didn't care whether or not it was a diamond or a moissanite. 

I also want to mention that I had to replace the moissanite once because it had cracked. My wife was doing some cleaning with the ring on and it caught underneath this metal piece and when she looked at it it had a crack directly through it that's something that would not happen with a diamond.
