Anglo American’s attempt to divest its iconic diamond division, De Beers, has stalled as major bidders withdraw amid a sharp decline in rough diamond prices. Former De Beers CEO Bruce Cleaver, who led a private consortium, confirmed he has abandoned his bid, citing an inability to justify the current investment economics. This retreat leaves the sale process—originally launched as part of a broader restructuring following a rejected takeover by BHP—facing significant headwinds as the market struggles with weak demand and the rise of synthetic alternatives.
The Collapse of the De Beers Bidding Field
The auction for De Beers, once considered the crown jewel of the mining industry, is shrinking. Bruce Cleaver, the former CEO, told Currency that he and his financial backers decided the timing was not right to acquire the business. “It felt like it was difficult to see an appropriate return on investment over the short term,” Cleaver stated. His exit follows reports that prospective bidders linked to the governments of Namibia and Angola have also stepped away from the process.

Industry observers note that only one major consortium, led by former De Beers executive Gareth Penny, remains active in the sale process. The dwindling number of participants raises concerns about the valuation of the brand. According to company filings, Anglo American has been forced to repeatedly write down the carrying value of De Beers, dropping from $9.2bn in early 2023 to just $2.3bn earlier this year.

De Beers’ ownership structure includes complex joint ventures with the governments of Botswana and Namibia. These partners act as shareholders, regulators, and tax collectors, creating a unique set of challenges for any potential buyer attempting to value the business.
Market Headwinds Facing the Diamond Sector
The difficulty in offloading De Beers is tied to a confluence of negative market factors. Rough diamond prices have remained depressed as the industry deals with a significant shift in consumer preferences. Cleaver pointed to several external pressures, including global economic uncertainty, fluctuating oil prices, and the impact of rising interest rates on discretionary spending.
Demand in China, a critical market for natural diamonds, remains subdued. Furthermore, the rise of lab-grown diamonds has permanently altered the competitive landscape. Natural diamond producers now face a market where they must compete with luxury giants like LVMH, Tiffany & Co, and Richemont, all of which invest heavily in branding and marketing, increasing the cost of entry for any new owner of the De Beers brand.
Structural Challenges and Long-Term Outlook
Despite the current difficulties, industry veterans maintain a cautious optimism regarding the long-term viability of natural diamonds. Cleaver emphasized that while the industry is in a “very tricky period,” he believes there will always be a space for natural stones. The fundamental question for future owners is whether the natural diamond industry has suffered permanent structural damage from the proliferation of synthetic alternatives.
The coexistence of lab-grown and natural diamonds is a central theme for the sector’s future. “I don’t think it’s plausible for them not to coexist in the future,” Cleaver noted. However, for Anglo American, the immediate priority is navigating an exit that has become increasingly complicated by the company’s prior public declaration that the diamond division is “non-core.” This admission has historically weakened the seller’s leverage, as potential buyers are aware of the vendor’s pressure to finalize the transaction.
Pro Tip:
When analyzing mining sector divestments, look at the “non-core” designation. Once a major corporation labels a unit as such, it often signals to the market that the seller is a motivated vendor, which can significantly impact the final sale price and negotiating timeline.
