When sorting the rough tanzanite, several steps are involved before one can achieve a gem worth selling. The first step involves picking the gems from their shaft. Once that is achieved, the gems are taken to the sorting house where they are cleaned and weighed.
The non-Gem materials are then removed from the gems, after which the gems are cobbled and graded into various groups. Good quality gems are processed more for color, clarity and carat grading. Once the gems have been graded and sized, they are packed and ready to be sold. What happens to the spare minerals The spare Tanzanite materials are taken back to laboratories by companies.

However, necessary structure was not in place, and quality of mined material diminished. That same year, the country was attacked by Uganda, which led to a two-year war.
Blocks A and C were awarded to large-scale operators, while Blocks B and D were reserved for local independent miners.

A level of sophistication was introduced to the industry. These businesses had the resources and tools to make tanzanite an international success. Tanzanite is mined approximately two hours outside of Arusha, the Tanzanian capital. From the mines, rough material is sold at buying offices in Arusha and in the outer villages of native Maasai. Next, it travels to cutting facilities, almost exclusively located in India. The finished gems are then sold to jewelry manufacturers and other retailers such as JTV.

Tanzanite stones are found in small pockets inside the boudins. Not every boudin will produce tanzanite, and many that do, contain low-grade material not useful for jewellery. Geological testing has shown that tanzanite layers exist down to meters below the ground. As mining levels drop deeper, increasingly sophisticated infrastructure is required to access the tanzanite. World-class infrastructure is put in place to secure the shafts, provide air supply and ventilation, watering and dewatering, to ensure the safety of the mine workers, and ensure that the tanzanite can be extracted safely and productively.
