This is an expensive gemstone in dollars per carat. It is clean and without flaws. Its tone is moderately rich and that is very important in Namibian blues. And an intense, consistent, saturated blue it is, in the shade of the midday sun. On the yellowish light of unnatural light, it shifts a little toward the blue green, but it is still a powerful color engine. I hear that the Germans and Chinese are bidding on larger blue Namibia rough and driving up the price so much that my days of having a change to get more to cut are over. Maybe I should work with a lesser gemstone like sapphire that usually finishes up blue after suitable treatments. It weighs 2.49 carats.
