Gemfields

Gemfields is a world-leading miner of coloured gemstones, specialising in emeralds mined from Zambia and rubies from Mozambique. It owns 75% of the Kagem emerald mine in Zambia and 75% of Montepuez Ruby Mining in Mozambique. The company states that it aims to operate responsibly, with transparency, legitimacy and integrity, and describes its mission as being the global leader in African emeralds, rubies and sapphires.

Gemfields acquired the Kagem emerald mine in Zambia in 2008, in partnership with the Government of the Republic of Zambia through the Industrial Development Corporation (IDC). The existence of rubies in Montepuez, in northeast Mozambique, became widely known in 2009; operations at Montepuez Ruby Mining began in 2012. Gemfields owns 75% of MRM, with the remaining 25% owned by Mwiriti Limitada, a local Mozambican company.
