Colored gemstone mining is a hard thing to pin down. The vast majority of mining is still done by independent, small-scale miners, working in remote locations and selling to buyers who pay cash and may or may not declare their gems on export. For many producing countries, particularly in Africa, the real production from the mines probably outstrips the reported production by a factor of 10 -- or 20, or possibly 100. No one really knows. In compiling this report, we've included estimates from both official and unofficial sources, but in some cases there simply isn't any information available. This report isn't intended as a comprehensive list of gemstone deposits; it's a guide to the most active mining areas in the world right now, with the humble acknowledgment that no matter how much we see, there's always more out there.
