Sightholders

Sightholders are chosen for their focus on Tanzanite, their ability to make a long-term commitment, their distribution capabilities, their understanding of the need for vertical integration and their operational standards of integrity.

TanzaniteOne has initially appointed eight Sightholders, with plans to increase this number in the medium term. These initial seven are listed below:
