Zambian Emeralds – Part 3

Our operational sites are based in remote locations, surrounded by small, rural communities.
We work collaboratively with these communities to develop and fund projects that will deliver long-term benefits for local people in health, education and livelihoods.
We build schools, provide health clinics and establish farming cooperatives, including women’s chicken farms, to empower and provide independence for local women.
We are careful to ensure that the projects we support are those that, once established, the community and local government will be able to sustain and develop on their own into the future.

Zambian Emeralds– Part 2

Zambian emeralds recovered at Kagem emerald mine are transferred to the sorting house, where they are cobbed by hand – small pieces of hard rock are carefully removed from emerald crystals. Lower-quality emerald-bearing rock is checked for crystallisation along picking lines and tumbled to remove waste rock. The emeralds are sorted and graded according to their colour, size, shape and clarity.

Zambian Emeralds – Part 1

It all starts at the Kagem emerald mine in Zambia. Kagem’s emeralds are found underground in hard rock. The dedicated team methodically search areas that display the characteristics necessary for emerald formation: where bands of pegmatite and high-grade metamorphic rock meet. They are experts at recovering emeralds by hand, enabling the safe recovery of some of the largest and most exceptional emeralds ever found.

There is of course another dimension to colour in rubies, in that the gemstone possesses pleochroism – the ability to display different colours when turned at different angles due to selective absorption of light. It is the skill of the gemstone cutter to marry these colours together and form the most pleasing, vivid crimson.
