Since the late 1960's, East Africa has been home to some of planet earth's greatest gem discoveries. And yet, little has been written about certain of these finds. In the autumn of 2007, Richard Hughes and friends set out to fill in the gaps, specifically regarding Tanzania's Mahenge, Songea and Tunduru regions.

A survey of the gem mines of Tanzania, including Merelani, Songea and Tunduru, based on Richard Hughes' 2007 trip.
