In the process of researching a diamond purchase online, a friend of mine who lives in NYC has repeatedly stressed that his dealer in NYC will sell at wholesale plus a small percentage. He seems to think that this will save me a lot of money over buying from WF or GOG. I''m concerned that I will pay less, but get less of a diamond. Does anyone have any insight into how much I am likely to save (or not) by buying from a dealer at a wholesale price vs. online? Are my concerns about being slightly taken advantage of legitimate? Or will the experience save me money buy making me realize that the superideal is not worth the premium? So many questions, thanks in advance for your input...
