De Beers has launched a business-to-business (B2B) pilot project for selling polished diamonds. The project will allow businesses to sell their diamonds in a new, direct way. De Beers Auction Sales (DBAS) will offer midstream diamond companies the chance to sell certain types of polished diamonds to other trade participants using its auction platform. This sales service for polished diamonds is an extension of the same service De Beers offers for rough diamonds. The rough diamond B2B sales pilot launched earlier this year.
