| [900] Chris Smith - Amazing Adventures with Tanzanite |
A year ago, there wasnt much new to be said about tanzanite, the oven-blued zoisite found only in its namesake country of Tanzania. Known to be benignly heated from brown to blue since its discovery in the mid-1960s, tanzanite was one of the gem worlds safer, most worry-free precious stones.

| [774] World Mining Report 2005 |
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, weve included estimates from both official and unofficial sources, but in some cases there simply isnt any information available. This report isnt intended as a comprehensive list of gemstone deposits; its a guide to the most active mining areas in the world right now, with the humble acknowledgment that no matter how much we see, theres always more out there....
