I am considering purchasing a loose stone from an internet site. I have looked at BlueNile, DirtCheap.., others. Although BlueNile is far from the least expensive, is anyone aware of insurance I can purchase to hedge against the possibility of not getting what I expect - or have PERSONAL experience (the good kind) with a particular site? I am even considering flying to Antwerp if I can make it worth my while - any thoughts? I am in the market for somewhere between a 1.75 and 2.25 stone.....thanks in advance, I am learning a lot here from you pros.
