Diamond beneficiation is the process that has transformed Botswana's economic landscape. The sale of diamonds has become a cornerstone of the nation's wealth, thanks to remarkable growth in adding value to these precious gems. Supporting The Local Cutting, Polishing, And Manufacturing Industries. The sale of diamonds is a major source of revenue for Botswana, greatly contributing to the nation’s overall wealth. Over the years, Botswana has witnessed remarkable growth in adding value to diamonds through a process known as diamond beneficiation. De Beers, Debswana, and the DTCB actively promote diamond beneficiation in Botswana through a comprehensive beneficiation strategy that extends its support to the local cutting, polishing, and manufacturing industries not only in Botswana but also in countries like Namibia and South Africa, where De Beers operates. By processing a considerable portion of the rough diamonds locally, Botswana ensures that skilled artisans and manufacturers have the opportunity to create a diverse range of jewellery designs for both domestic and global markets. Consequently, the local diamond beneficiation initiative not only nurtures the expansion of Botswana's jewelry industry but also actively contributes to its economic progress. Despite the local processing, a majority of the rough diamonds sourced from Botswana ultimately find their way to cutting and polishing facilities around the world. These facilities play a crucial role in transforming the rough diamonds into exquisite jewellery pieces that cater to the demands of the international market.
