I was wondering, what do stone dealers do? Do they buy big lots of faceted gems and then find good ones and sell those? Do they buy rough and send them to cutters? I understand what cutters do and the value they clearly add by cutting, and I also understand that specialist dealers find unique stones to give you a large selection of a rare kind of stone, as many of the dealers in the sticky, but I don't get the range of practices, for example, between multicolour versus DB versus ebay "stone flippers".
