Have you ever wondered how emeralds are mined? 

It takes a huge amount of investment, skill and hard work to mine an emerald.
From the work of the geology team to mining experts, the wash plant, sorting and grading - every step of the process demonstrates the enormous extent of the input at Kagem Mine in Lufwanyama, the largest known emerald producing mine in the world.
Kagem is operated by London-based Gemfields, the world’s leading supplier of coloured gemstones, which owns 75 per cent of the mine in a model partnership with the Zambian government.
