Tsavorite has become a very desirable gemstone
The vivid green is radiant with a colour range from a springlike light green, an intense blue-green and a deep forest green all these colours stimulate our senses. The stone has a high refractive index this the measure of the bending of a ray of light when passing from one medium into another. This is what gives the stone its brilliance. Like all stones the quality will vary with the rock it is cut from. The higher end stones will end up fetching much more than the lesser quality stones.

Naming a gemstone has certain rules, modern mineralogical methods suggest gemstones should end in "ite" and since the stone's discovery in the Tsavo National Park with the Tsavo river running through, the former president of Tiffany & Co Henry Platt proposed the name Tsavorite. This was the same man who had named Tanzanite which was discovered in 1967 not very far away in Tanzania.
The Tsavo National park has an abundance of wildlife and mining the stone can be dangerous due to the odd lion in the area and the several species of dangerous snakes.
