De Beers is moving part of its sorting operation from its traditional home in London to Botswana’s capital, Gaborone, The BBC reports.
The operation being moved is known as aggregation and involves sorting stones from different countries by size, shape, color, and quality.
Aggregation has been carried out at De Beers headquarters in London since the 1930s. About 50 jobs will be lost, The BBC reports.
De Beers opened a diamond processing plant in Botswana earlier this year. The country is the world’s largest producer of diamonds and is also a major shareholder in De Beers.
