- Tsavorite - Tsavorite is a green coloured garnet, first discovered by a British geologist, Dr Campbell R. Bridges in 1961 in Zimbabwe while working for the United Kingdom Atomic Energy Authority.
Unable to obtain a mining permit, he began prospecting in Tanzania and in 1967 made a second discovery of Tsavorite in northern Tanzania in 1967. Dr Bridges commenced mining the deposit, but the mine was nationalised by the government, so Dr Bridges moved to Kenya, where he made a third discovery of the mineral at the end of 1970.
Tiffany & Co. began promoting the then unnamed mineral in 1973 in association with Dr. Campbell, and it was agreed it should be named Tsavorite, after the Tsavo National Park in Kenya, near to where it was mined.
Dr Bridges died aged 71 in 2009 on his property in Tsavo National Park, Kenya, when he and his son were attacked by a mob in a dispute over mining rights.
