Hello!
I just want to collect the writer of this post....
Im a Tanzanian, i know well about Tanzanite....Tanzanite not available in Mt. Kilimanjaro, Tanzanite is available in Arusha region, the place called MERERANI...! Is where that Gemstone called Tanzanite is available......the region where Mt. Kilimanjaro located and the region where Tanzanite available is neighbour Regions so most of abroad citizens they got confused!

In Tanzania we have a lot of Gemstones and Minerals, like Tanzanite, Diamond, Amethyst, Ruby, Gold, Copper, Nickel, Zinc, Urannium and more, but Tanzanite is high expensive more than others.

The Tanzanite market price for now in Tanzania its about $ 500 - $ 600 per 1 gram if you buy from local miners....
Thanks.

NB:
Sorry for the grammar mistake, English is not my language, it came in Africa by Ocean!
