I am going to buy an engagement ring real soon. My girlfriend said she wants a oval, but i don't know if there is a difference. I read the web site and am quite confused, so I was wondering if anyone could tell me how much (any ballpark figure would help) i would pay for a oval diamond, probably around a carat or a little less on a somewhat plain platinum band. I am nervous about going shopping for the fear of "car salesman" techniques and I will probably get taken to the cleaners......any help would be GREATLY appreciated....john
