According to "Ruby and Sapphire" by Richard W.Hughes, "The deposits were discovered in 1973 when American geologist Jon Saul and Elliott ('Tim') Miller were prospecting in Kenya's Tsavo West National Park for chromium and vanadium bearing gemstones when they found what has become one of the world 's richest deposit of ruby.This ruby will fluorescence well and can be similar to Burmese Rubys
A Ruby is a pink to blood-red gemstone a variety of the mineral corundum (aluminium oxide]. The common red color is caused mainly by the presence of the element chromium. Its name comes from ruber, Latin for red. Other varieties of gem-quality corundum are called sapphires. Prices of rubies are primarily determined by color. The brightest and best "red" called pigeon blood-red, commands a huge premium over other rubies of similar quality. After color follows clarity: similar to diamonds, a clear stone will command a premium, but a ruby without any needle-like rutile inclusions will indicate that the stone has been treated one way or another. Cut and carat (size) also determine the price
