The Tanzanian president, John Magufuli inaugurated what was named a « wall of protection » encircling the Tanzanite mines on April 6th. Work began in November 2017 and ended with two months advance in February 2018 for a total cost of 3.5 million dollars. This wall, measuring 24 kilometres and protecting a surface of 82,2 square kilometres can resist floods and also has security cameras. Sophisticated instruments allow the detection of all hidden gemstones, even those swallowed by the minors! This wall is of one of the propositions held in the « Tucson Tanzanite Protocol » drafted in 2003, the goal of which being to reposition ethical matters at the heart of the business. In light of these new measures, the minors employed previously under precarious daily contracts are now given work contracts and have identity cards they must present to access the mines.
