Anglo American is bracing for another writedown of its De Beers diamond unit due to persistent weakness in the diamond market. The miner's strategic review includes a potential sale or listing of De Beers. This follows a challenging period for the diamond industry, marked by fluctuating prices and shifts in consumer demand.

The news comes as Anglo American progresses with its proposed mega-merger with Teck Resources. This deal will reshape the mining landscape, and the financial performance of De Beers is a key factor. Investors are closely watching how the diamond unit's valuation will impact the overall transaction and the company's future prospects.

The diamond market faces headwinds, including competition from lab-grown diamonds and global economic uncertainties. Anglo American's decision to potentially divest or list De Beers reflects a broader industry trend of adapting to evolving market dynamics. The miner will likely release more details on its plans soon.
