Sights — The De Beers Periodic Rough-Diamond Sales
Sights — The De Beers Periodic Rough-Diamond Sales
Ten cycles a year of pre-allocated boxes, held in Gaborone since 2013
Sights are the periodic sales events at which De Beers, through its rough-marketing organisation, offers pre-allocated boxes of rough diamonds to its contracted sightholder clients. Held approximately ten times each year, the sights are the operational mechanism by which the sightholder system delivers rough into the cutting trade, and they are the principal scheduled rhythm of the upper-tier rough market. The term itself refers to the practice of viewing the goods on offer before acceptance — the sightholder is invited to see what is being allocated, but the assortment is built by De Beers and the buyer's discretion is structured rather than open.
Schedule and location
The sights run on a published cycle of ten per year, with each sight typically lasting around a week. Since November 2013, the principal sales operation has been based in Gaborone, Botswana, where De Beers's beneficiation agreement with the Botswana government locates rough aggregation, sorting, and the sales floor. Earlier in the system's history, sights were held in London at Charterhouse Street, and a long generation of trade memory associates the term with that site. A smaller secondary operation services parallel activity in Antwerp and other centres, but the principal box allocation is at the Gaborone sight.
What happens at a sight
In the days running up to a sight, the rough sorting floor builds out the boxes for each sightholder according to the contracted assortment profile and the run-of-mine production for the period. Each sightholder receives an itinerary specifying the goods on offer and the time window during which inspection takes place. At the sight itself, the buyer and the buyer's evaluators inspect the box, verify the assortment and weight, and accept or, in limited cases, decline the box at the published price. Boxes are not negotiated — the price is set by De Beers — but the sightholder may make limited representations on assortment matching to manufacturing programme.
Pricing and disclosure
Box prices are set by De Beers in advance of the sight on the basis of the company's read of the rough market, the polished trade conditions, and inventory considerations. Aggregate sight sales totals are reported by De Beers in its periodic results, and the trade press tracks the sequence as a leading indicator of rough conditions. Individual buyer detail is not published, but cumulative data is available and the major rough-market data services build their indices in part from sight reporting.
The sight calendar in the trade
For the cutting centres, the sight calendar structures cash flow, manufacturing planning, and bank facility utilisation. Sightholders raise lines of credit calibrated to box-price commitments, and the rhythm of sight-to-polished-output cycles is the foundational planning unit for cutting operations. The polished trade, in turn, takes its supply pipeline from the cutting centres' sight cycles, and the major retail launches are timed against expected polished availability from the corresponding sight production.
Modern adjustments
De Beers has supplemented the sight programme with online rough auctions through its Auction Sales business, which provides a partial spot-market alternative for non-sightholder buyers and a published reference price curve. The sight programme remains the principal channel for sightholder allocation, but the auction route has reduced the absolute weight of the sight in the rough market and improved price transparency. The 2020 to 2023 period saw further adjustment to the sight model in response to pandemic-era and lab-grown competitive pressure, with reported flexibility on box deferral and assortment matching.
