There is a diamond outlet at the Premium Outlets, also Kohls although they are a department store have very good prices on diamond rings. A guy was buying an engagement ring there at Christmas when we were there and couldnt help looking (as you do) to see what they were like and they did look very reasonable. If he wants to make it even more special tell him if he takes her to Discovery Cove, the can get the dolphin to ask her, they swim up them with a special buoy.
