That's easy to claim. Ever done a blind test?

Anyway, I imagine no jeweler when asked to clean a stone, is going to blurt out "That's not a diamond!" No positive customer reaction possible there.

Rutile - http://cdn.shopify.com/s/files/1/0744/0957/articles/JC8_1d1c... highest RI out of pretty much anything. Insane fire.

Moissanite - https://www.dhresource.com/0x0/f2/albu/g9/M01/71/E4/rBVaVVy8... Higher RI than diamond but less than rutile. Still great fire.

Diamond - http://img.fruugo.com/product/1/70/74615701_max.jpg Pretty plain and dull. Hardly any prismatic/chromatic display. Even CZ has more 'fire' than this.

We did blind tests when we were shopping for rings. It was stupidly easy to tell - moissanite sparkles more. Didn't go the way the jeweler wanted, though - he only sold diamonds, but had a moissanite ring he was cleaning for a customer for comparison, and we liked the moissanite better.
