Do people have any recommendations for questions I should be asking internet diamond brokers about stones I am interested in? I am shopping for a high quality emerald cut stone. Can the salespeople typically provide any additional dimensional info (e.g. crown height, angle)? What about firescope images? When having a stone sent to an appraiser before paying for it, it is ever possible to have 2 sent for comparison? The process of honing in on a good cut seems so daunting, especially with fancy cuts.
