My wife loves moissanite, we went with etsy and even got her wedding band custom designed in CAD to fit your engagement ring. Manhattan box was the store we used for the band and a UK spot called shinyjungle for engagement ring where she liked a lab grown morganite. She gets a lot of compliments on them. Most cant tell the difference between them and traditional blood diamonds. Cubic zirconia or epoxy based stones are what you dont want.
