The sorting process will start by removing the gemstones from the shaft; it will then be taken to be cleaned and weighed before it goes to the cobbing part of the process. Once the gemstones have been cobbed and graded theyre placed into different groups according to their quality. Afterwards high quality tanzanite packed and ready for purchase.

Initially, tanzanite was easily collected from the surface, but scavenging mining didnt last long and pits and tunnels quickly took preference. Geological testing has shown that tanzanite layers exist down to 200 meters below the ground. As mining levels drop deeper, increasingly sophisticated infrastructure is required to access the tanzanite.
