If you want to buy some sparkly jewelry to signify engagement I highly recommend moissanite. It looks better than Diamond because it is double refractive. Also, no one will be able to tell a difference. 3 times I've taken my wife's rings to jewelery stores to have it cleaned or have a small stone replaced and every time I have to tell the Jeweler that it is moissanite. If you do tell people it is moissanite be prepared to hear "Didn't you want a 'real' stone?' or " It looks dirty " especially from Jewelers.
