Welcome to The Inquiry. I'm Charmaine Kosia.
Each week, one question, four expert witnesses and an answer.
August 2024.
Gaborone, Botswana.
The country's president at that time, Mugwetsi Mosisi,
sits at a desk, eyes closed, surrounded by reporters and cameras.
He's moments away from being one of the first people to hold the second largest diamond ever discovered in a mine.
It weighs around half a kilogram.
In recent years,
all of the world's most supersized diamonds have been mined in the southern Africa country.
But now the industry that has underpinned the economy for decades is under threat from gemstones grown in labs.
So this week we're asking, are diamonds forever in Botswana?
Today, Botswana,
it is the second after Russia in terms of its importance in diamond mining.
Gloria Sumalekai,
I'm the executive director of the Botswana Institute for Development Policy Analysis.
It's a government think tank.
I used to be the deputy minister of finance.
Botswana was a completely rural country,
and the mainstay of the economy was subsistence agriculture.
