2) Whereas each colored gems has its own individual color identify.For example for blue color the range of blue will be intense blue, royal blue, cornflower blue. Each color has its own price range.It is very rare to be able to select a colored gem with 10 pieces having a uniform color. Therefore if you can find 10 pieces with uniform color shade, the price will be very high, even more expensive than diamonds.

Diamonds price are fixed according to the Rapaport Price List which is the primary source of diamond prices and market information.

Why are diamonds not that rare? Debeers control the world’s diamond prices. There are hundreds of diamond mines in the world.
But there is a very interesting fact about colored gems, for instant Tanzanites are only mined in the one and only mine on earth…. in Melarani Hills in Tanzania. You cannot find tanzanites in any other parts of the world!!
And also Green Tsavorite Garnets are mainly found in Kenya. A very minimum output was discovered in Tanzania but main production output is from Kenya. Both countries are neighbors.
