Diamonds mined in Botswana should be polished locally: President Boko
Botswana President Duma Boko has called for a significant policy change in the country’s diamond industry, urging that all diamonds mined in Botswana be cut and polished locally before export. This move is intended to maximize the economic benefits of the nation’s mineral wealth and stimulate job creation.
Policy Shift: President Boko stated that no mineral will leave this country without being processed, emphasizing that diamonds and copper concentrate must undergo local value addition before export.
Current Practice: Currently, most of Botswana’s rough diamonds are sent to India and other manufacturing centers for cutting and polishing. Efforts to establish local factories have faced challenges due to high operational costs.
Government Initiative: The president made these remarks in Setswana at a community meeting in Ramotswa, highlighting the government’s commitment to a robust beneficiation program aimed at transforming the national economy The announcement was reported by The Projects Magazine and shared on its Facebook page, reaching a wide audience.
Polishing all Botswana diamonds locally, as recently urged by Botswana’s president, could have significant implications for India’s diamond polishing industry, though the immediate impact may be limited and gradual. If Botswana mandates that all rough diamonds be cut and polished locally before export, India’s diamond manufacturers would receive less Botswana-origin rough, potentially reducing their raw material supply
Botswana is one of the world’s leading diamond producers. Historically, the country has exported rough diamonds for processing abroad, missing out on added value and employment opportunities at home. The government and De Beers have previously attempted to attract investment in local manufacturing, but progress has been slow.
President Duma Boko’s call for all Botswana diamonds to be cut and polished locally marks a bold step toward economic transformation. If implemented successfully, this policy could reshape the country’s diamond industry and set a precedent for other resource-rich nations.

CVD Synthetic Fashioned To Imitate A Rough Natural Diamond
The Near-Colorless Stone Is Believed To Be The First Time Creators Of A Synthetic Chemical Vapor Deposition (CVD) Diamond Have Shaped It To Resemble A Rough Diamond
The 6.87-carat near-colorless CVD diamond was shaped to resemble a natural rough octahedral crystal but showed distinct synthetic features under microscopic and spectroscopic analysis.GIA’s tests confirmed the stone’s synthetic origin, noting polishing marks, facet junction roughness, and luminescence patterns inconsistent with natural diamonds.
No evidence currently suggests widespread substitution of synthetics for rough natural diamonds, but existing detection tools could be adapted if such cases increase.
The near-colorless stone is believed to be the first time creators of a synthetic chemical vapor deposition (CVD) diamond have shaped it to resemble a rough diamond, according to an article in the spring issue of the institute’s Gems & Gemology quarterly journal.
Upon investigation with the use of raman spectroscopy, the results confirmed that the material was a diamond, with its near-octahedral shape similar to that of a natural rough crystal. Further analysis showed that it was not a true octahedron, as only one set of opposing faces was parallel. Microscopic observation under differential interference contrast revealed extremely flat faces marked mainly by parallel polishing lines, unlike the growth steps and trigons typically seen on natural octahedral faces. The facet junctions were extremely rough, possibly due to measures taken to improve the color, after which the main faces appear to have been repolished, the institute explained.
