Hi everyone! I do know a little bit about diamonds- probably just enough to get myself in trouble though. I saw a blue square cut diamond ring on the web I thought looked really neat and thought it would make me a nice wedding ring. I really don't know too much about this cut and was hoping someone here could tell me about it and it's good points and I guess bad points too. Also how big is this .48 carat diamond in centimeters? Thanks!
