De Beers Q4 production drops 35%
De Beers reported a staggering 35% drop in Q4 2025 production, recovering just 3.78 million carats. The primary culprit? A strategic retreat in Botswana, where output plunged 56% as the company kept the world-class Jwaneng and Orapa mines offline for maintenance.
Key Financial Takeaways:
- The Botswana Blackout: Jwaneng remained completely offline, a deliberate move to curb inventory buildup amidst sluggish global demand.
- A “Loss-Making” Year: Parent company Anglo American warned that De Beers will likely be in the red for FY2025, potentially triggering a third valuation impairment in three years.
- Guidance Cut: Citing “geopolitical and tariff uncertainty,” De Beers slashed its 2026 production target to 21–26 million carats (down from ~29 million).
While Canada’s Gahcho Kué mine provided a rare spark (output doubled on high-grade ore), the broader picture is one of managed decline. Anglo American continues its push to divest its 85% stake, leaving the diamond titan in a high-stakes transition period. The prolonged downturn has prompted Anglo American to warn of a potential third impairment of De Beers’ value in three years. Anglo noted that De Beers is expected to be loss-making for the 2025 financial year.

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.
