Since the first discovery of a diamond in Namibia by Zacharias Lewala, the stones have played an important role in the history of the country. The myth goes that the first diamonds were just lying on the ground, ready to be picked up by anyone; sparkling in the Namibian sun and ready to be set in a piece of jewellery. The reality is a little different to the myth and this embodies Namibia Diamond Trading Company?s mandate. Diamonds are extracted from the earth, either on land or more frequently these days at sea, off the coast of Namibia. These ?rough? precious stones enter a series of processes or the ?diamond pipeline? in which the NDTC plays a pivotal role in determining their value. The first step in determining the authenticity of a diamond is cleaning. Every diamond is unique and has different properties, but one common property is that diamonds can withstand acidic abrasive chemicals because they are the hardest natural substance known to mankind. These chemicals wash off all the dirt and debris on the stones and leave the diamond intact. Non-diamond stones are destroyed in the process and only real diamonds survive .
