De Beers cuts Sightholder list by a third in landmark restructuring
More than 20 clients dropped as the miner reshapes its rough-diamond distribution network
De Beers has notified more than 20 of its 69 sightholders that their client relationships will not be renewed when new contracts take effect on 1 July 2026 — a reduction exceeding one-third of its trading roster and the deepest single-cycle cut in the company’s recent history.
The revised sightholder list stands at approximately 45 companies, varying slightly depending on how firms with multiple trading divisions are counted. New contracts will replace agreements originally signed.
The restructuring reflects a strategic pivot toward a leaner, more concentrated distribution model. Industry analyst Edahn Golan has noted that at least one new sightholder from India has been added to the roster, signalling a continued shift in rough-diamond purchasing toward South and East Asian cutting centres.
De Beers declined to confirm the full list of retained or terminated clients, stating through spokesperson David Johnson that the updated sightholder directory will be published on the company’s website when the new contracts commence in July.
At its peak in the 1970s, De Beers maintained a sightholder list of over 350 companies. The move to sub-50 clients marks a structural consolidation that mirrors broader pressures on the natural diamond trade, including sustained demand softness, competition from lab-grown stones, and margin compression across the midstream.

Pandora Adds Carbon Footprint Labelling For LGDs
New Level Of Transparency Empowers Consumers To Compare Climate Impact Of Their Diamond Jewellery
For decades, diamonds have been graded by the traditional 4Cs: Cut, Colour, Clarity and Carat. Now Pandora is adding the 5th C, declaring the carbon footprint of every Pandora Lab-Grown Diamond as part of the product information on pandora.net alongside the traditional four grading criteria.
The carbon footprint covers all emissions from the diamond crafting process: from producing the raw materials used to grow the diamond all the way until it is cut and polished, ready to leave the diamond facility.
As an example, a one carat Pandora Lab-Grown Diamond has 12.58 kg of CO2e emissions. This is around 90% lower than a mined diamond of the same size.
By adding carbon footprint to the diamond conversation, Pandora gives customers an extra point of comparison and essential insight into the climate impact of their desired diamond jewellery.
CARBON FOOTPRINT COMPARABLE TO A PAIR OF JEANS
Lab-grown diamonds are chemically, optically, thermally and physically identical to mined diamonds.
Pandora stopped using mined diamonds in 2021 and is now only using lab-grown diamonds made with 100% renewable electricity and set in jewellery crafted from 100% recycled silver and gold.This significantly reduces the carbon footprint of the Pandora Lab-Grown Diamonds collection. For example, a 14k gold Pandora Infinite ring with a 1 carat lab-grown diamond has a comparable carbon footprint to a pair of jeans.
PANDORA TO SHARE FINDINGS
The carbon footprints of Pandora’s lab-grown diamonds have been calculated by external life-cycle assessment experts and published in a study verified by auditing firm EY. The study uses best practice methodology and is available on pandoragroup.com.
Adding a 5th C is a response to increasing consumer expectations to sustainability, and Pandora will share its methodology and findings with other jewellery makers to inspire greater transparency across the sector.
Pandora Lab-Grown Diamonds are currently available in the US, UK, Canada, Australia, New Zealand and Denmark with more countries to be added soon.
