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.

Natural Diamond Council Launches World Diamond Day on April 8, 2026
A new global moment to share the stories behind natural diamonds on April 8.
The Natural Diamond Council (NDC) introduces World Diamond Day on April 8, 2026, a global movement that brings people together through the stories behind natural diamonds.
On this day, everyone is invited to participate, from those who work with diamonds every day to those who wear, gift, or admire them. World Diamond Day is about sharing the personal and meaningful moments that natural diamonds represent.
Across social media, participants are encouraged to post a photo or short video that captures what natural diamonds mean to them, whether it is a milestone, a memory, a piece of jewelry you love, or the journey behind it.
On April 8, simply share your story using #WorldDiamondDay and #NaturalDiamonds to join a global wave of voices celebrating something authentic.
Stories can take many forms:
– Personal moments such as engagements, anniversaries, and heirlooms
– The journey of a diamond from origin to artistry
– Positive impact in communities, education, and conservation
– Design, craftsmanship, and finished creations
World Diamond Day is a collective moment and not a campaign. It is shaped by the people who participate, from personal milestones to the communities diamonds uplift and transform. It is a chance to see natural diamonds through the lens of real people and real stories shared around the world in real time.
In a world where so much feels easily replicated and fast, natural diamonds are enduring symbols of love and connection. Formed over billions of years, they carry memory and human meaning. World Diamond Day brings those stories into view from every corner of the world.
Everyone is encouraged to take part by sharing a story that feels personal and true. Organizations and businesses can also amplify the movement by inviting their teams, partners, and communities to participate.
Worn. Given. Passed down. Never forgotten.
On April 8, the story of natural diamonds belongs to everyone.
