ABSTRACT
The article discusses the gemological properties of the rough ruby and pink sapphire deposits shown at the February 2005 Tucson gem shows. The stones were mined from the Kenya Rift Valley in the west-central part of the country. These stones were initially shown to a local gem prospector in October 2001 by members of the Tugen tribe who lived in Barsemoi. The prospector applied for a license with the Kenya Commissioner of Mines, and after a two-year process received a mining permit. In June 2004, he resumed collecting surface material from the site and has obtained more than 2 kilograms of corundum. It is inferred that approximately 400 local villagers were active in the region surrounding the original mining claim, expanding the corundum-bearing area to approximately 20 square kilometers.
