Tanzania has recorded increased revenues from sales of tanzanite, which authorities attribute to the 24km perimeter wall surrounding the mines in Mirerani in the northern Manyara Region, constructed in April to curb smuggling of the rare gemstone.
Tanzanite revenues rose to Tsh1.28 billion ($460,987) in September, from a low of Tsh166 million ($74,439) registered in January 2015, thanks to new laws and regulations that have seen better reporting of exports and increased payment of royalties to the government.
