ROUGH DIAMOND SALES and DISTRIBUTION
Global rough diamond sales by producers increased approximately five per cent from 2012 to 2013, to reach a total of just under US$18 billion. De Beers remained the largest supplier with roughly 33 per cent of overall sales measured by value (the same share as in 2012), followed by ALROSA with 25 per cent of sales (vs 23 per cent the year before). De Beers uses multi-year contracts with approximately 80 term contract clients - Sightholders - to sell most of its production. De Beers has also used sophisticated online auctions since 2008 to sell a proportion of the Group’s production.
Supply through term contracts with a number of selected customers seems to be the preferred mode among suppliers offering a relatively stable volume and mix of goods, often supplemented by auctions, especially of large stones.
