Bundling.
The DTC - De Beers' selling and
marketing arm - processes some two thirds, by
value, of the world's diamond production. All diamonds are sorted and valued into over 16,000 categories
of shape, quality, colour and size by highly-skilled staff. The diamonds are sold by the
DTC at regular sales called
"sights" to the world's leading diamantaires.
Once sorted, diamonds are blended into
'selling mixtures' in
preparation for sale to the DTC's 120 or so clients, or Sightholders as they are also known, comprising the most experienced diamond
polishers and dealers in the
world.
