Tanzanite Mining

Tanzanite is commercially mined in only one small area in the Mererani (or Merelani) Hills in Northern Tanzania, at the foothills of Mt Kilimanjaro. Originally, Tanzanite could easily be collected on the surface, but scavenger mining quickly gave way to pits and now tunnels, some of which extend hundreds of meters beneath the surface. The Tanzanite Experience has its own mine located in Block D and follows a code of strict ethical mining and best practice. This ensures that the best of the Tanzanite’s properties are preserved.

From 1967, an estimated two million carats of Tanzanite were extracted before the mines were nationalized by the Tanzanian government in 1971.

In 1990, the Tanzanian government split the mines into four sections: Blocks A, B, C and D. Blocks A and C were awarded to large operators, while Blocks B and D were reserved for the local miners

In June 2003, the Tanzanian government introduced legislation banning the export of unprocessed Tanzanite to India (like many gemstones, most Tanzanite was being cut in Jaipur). The ban was an attempt to encourage development of local skills in order to boost the economy.

In 2010, the government of Tanzania banned the export of rough stones weighing more than one gram.
