Where did you find the moissanite?

My wife wants to upgrade her diamond and I think she is convinced that moissanite is a good substitute.

But I find that moissanite is still far more expensive than I expected (for 1.5 carats, it wasn't 2% of the price of a diamond).

But maybe I'm looking in the wrong places.

If you don't mind me asking. Where did you find yours?
