On 1928 and what was missed
In 1928 a colonial geological survey working in the kafubu area near the ndola rural district of what was then called northern rhodesia noted the presence of beryl mineralisation in the ground.
beryl. the mineral family to which emerald belongs.
they noted it. they recorded it. and they moved on.
for approximately forty years — through the copper boom, through independence in 1964, through the first years of kenneth kaunda's zambia — those stones sat in the ground. 500 million years old. formed in the precise geological conditions of the copperbelt schist belt where chromium-bearing rock met beryllium-bearing fluid deep in the earth and produced, slowly and over geological time, one of the most coveted gemstones on the planet.
noted in 1928. left.
it was zambian miners in the 1970s who changed that.
working the kafubu ground with the specific knowledge of people who lived near it and understood it, they began finding stones. not beryl in a survey report. emeralds. commercial quality. extraordinary colour. the deep slightly bluish green that would eventually make the zambian emerald one of the most recognisable and sought-after stones in the world.
the government established kagem in 1984. gemfields arrived in the 2000s. the mine grew into the largest emerald operation on earth. in march 2020 a single cluster was recovered from the chama pit weighing 187,775 carats — one of the most extraordinary emerald finds in recorded history.
all of it from the same ground.
the ground that a colonial survey glanced at in 1928 and moved on from.
the ground that zambian miners looked at more carefully.
and found what was actually there.
this is not a small detail.
it is the whole story. 🇿🇲💚
