We are getting ready to launch and scale GemFair, a pilot project that aims to create a secure and transparent route to market for ethically-sourced artisanal and small-scale mined diamonds. By providing artisanal and small-scale miners with access to the global market and offering fair prices, GemFair hopes to improve miners’ livelihoods and foster the sector’s development as a credible and trusted source of diamond supply.

As one of the early employees in this new initiative, you will have the opportunity to take an active role in strategic decisions and the overall direction of the venture.
