What makes Lannyte superior to Moissonite?

Simply stated, Lannyte most closely resembles a diamond. In fact, without performing a specific gravity test or examination under a high-powered microscope, even accredited gemologists have difficulty recognizing that Lannyte simulated diamonds are not natural!
Moissionite is also a lab-grown simulated diamond.  After a little research on your own, you will see that most agree about it’s inclusions and greenish yellow color due to it’s carbon base.  In addition, moissonite is priced like a natural diamond.  Lannyte’s refractive index(that which gives stones their sparkle) is closest to a natural diamond.  Like diamonds, Lannyte is singly refractive, whereas Moissonite has a double refractive index.
