Namibia Diamond Trading Company (NDTC) is a 50:50 joint venture between the Government of Namibia and De Beers Namibia Holdings which was formally conceived in January 2007 following an agreement to sort, value and market Namibian diamonds. While it serves as Namibia’s prime avenue to recognise and formalise the efforts of the Namibian Government and De Beers to develop a sustainable local downstream diamond industry, NDTC can trace its roots back to 1988 when the first sorting and valuation activities were established.

These activities were through DTC Valuations Namibia, a wholly owned De Beers company which was tasked with the sorting and valuing of Namibian diamonds until the inception of NDTC in January 2007. Today, NDTC prides itself as Namibia’s flagship diamond sorting and valuing brand, contributing significantly to national growth and a sustainable future.
