Diamond vs. Morganite

Ma

I'm looking into getting my "real" wedding set (I currently have a cheapy set) and I love love love Morganite, but I want to know y'alls opinions. Is Morganite as good as diamond in terms of quality? Will it last as long? Should I spring for the waranty or just stick with a traditional diamond ring?

I'd also love to see your sets! Give me some ideas! Tia!
