DTC Botswana

Diamond Trading Company Botswana is the world’s largest rough diamond sorting and valuing operation.


DTC Botswana is the world’s largest and most sophisticated rough diamond sorting and valuing operation, with a capacity to sort 45 million carats a year. It is a 50/50 joint venture between De Beers and the Government of the Republic of Botswana.

Its mission is to be a centre of excellence for sorting and valuing diamonds, turning Botswana’s diamond dreams into lasting reality.

It handles the rough diamond production of Debswana and aims to drive and support the creation of a vibrant, sustainable and profitable downstream diamond industry in Botswana through superior sorting and valuing practices.

Its activities help add value to the local diamond industry through the cutting and polishing of diamonds, leading ultimately to the manufacturing of jewellery.

DTC Botswana opened in 2006 with the aim of providing a regular supply of diamonds for local manufacture by Sightholders and aims to be a world leader in domestic beneficiation.

It sorts rough diamonds according to the 4Cs - carat, cut, clarity and colour – into around 11,000 categories. The sorting process ensures the correct valuation of all mines’ production and delivers a consistent assortment of diamonds to DTC Botswana’s clients – De Beers Global Sightholder Sales and Okavango Diamond Company.
