This gem is considered "new" because it was
first discovered in the 1960s, however it was created millions of
years ago and is found only between Kenya and Tanzania.
The discovery is almost like something out
of a fairytale. In 1967 whilst prospecting for gemstones in
Tanzania, British geologist Campbell R. Brides came across an
unusual shaped stone. Inside he found stunning green grains
and crystals. After gemmological tests were conducted, it was
announced that the find was green grossularite, a member of the
garnet family.

Many experts clambered for this wonderful looking gem (including
Tiffany & Co. in New York) however at the time obtaining an export
licence was impossible. Not wanting to admit defeat, Campbell
Bridges went in search of other sources of the stone. This
proved to be difficult as the Earth's plates which were moving
around a lot damaged much of the gems.
It wasn't until 1971 that another lot of
these green gemstones were found in Kenya, where he was then able to
register his find and could start exploiting the occurrence.
Finally by 1974, Tiffany started to use and
promote Tzavorite in the USA.
Green
Grossularite Garnet
This gem stone is a form of grossularite garnet but is called
Tsavorite. This is because when naming gemstones now, the gem must
end in "ite". Because the gem was found in Tzavo National Game
Park, Henry Platt (former president of Tifany & Co) suggested the
name Tsavorite. However it is also referred to as Tzavolith as
"lith" means "stone" in Greek.
The vivid green of this stone have made
Tsavorite highly desirable. Unusually, this gem does not
require to be heated or oiled. Also Tsavorite is extremely
robust and is less likely to become damaged or splinter.
Tsavorite also lends itself well to "invisible settings" which
allows the stones to be set close together. This is not
possible with Emeralds.
What is especially stands out about Tsavorite (besides it's beauty)
is the price. Compared to Emeralds, Tsavorite is very
inexpensive. This is largely due to the general public not
being aware of this beautiful gem's existence. However
Tsavorite has many advantages over Emeralds and is much more rare.
As a result Tsavorite could well be a wise investment.
