The shining green tsavorite is a young gemstone with a very long geological history.
Its home is the East-African bushland along the border between Kenya and Tanzania.
Tsavorite is one of the sassy gemstones in the Jewlery industry. Leafy Green not like emerald and neither like tourmaline. Its typically different Green color makes it so identifiable.
Finding Gemstones are always been a thing in history. And again tsavorite carries great story about its findings. Lets learn some more about this
The few mines lie in a uniquely beautiful landscape of arid grassland with bare, dry hills. It's dangerous country, the habitat of snakes, and now and then a lion patrols, on the lookout for prey. There, near the world-famous Tsavo National Park, that history began.
In 1967 a British geologist by the name of Campbell R. Bridges was looking for gemstones in the mountains in the north-east of Tanzania. Suddenly he came across some strange, potato-like nodules of rock. It was like a fairy-tale: inside these strange objects he found some beautiful green grains and crystal fragments. A gemmological examination revealed that what he had discovered was green grossularite, a mineral belonging to the colourful gemstone group of the garnets, and one which had only been found on rare occasions until then.
It was of an extraordinarily beautiful colour and good transparency. The find made the specialists sit up and take notice; Tiffany & Co. in New York also soon showed an interest in the newly discovered green jewel. However, in spite of all efforts, it was not, at the time, possible to export the stones from Tanzania. But Campbell Bridges was not one to give up easily. As a geologist, he knew that earth strata bearing gemstones were not necessarily limited to one particular area, indeed that they could extend over much greater areas - and in his opinion the stratum he had found was just such a one. For the rock belt in which most of East Africa's gemstone mines lie is very ancient.
It began to form many millions of years ago, while the continents were still very much on the move. At that time, the area concerned had actually been under the sea. The sedimental deposits between the continents were greatly compressed and folded as a result of the movement of the massifs. Through tremendous pressure and at high temperatures, the rocks which had been present originally were transformed.
