The latest sales data from De Beers reinforces why this is one of the worst years for the diamond industry in a long time.
The Anglo American Plc subsidiary reported sales on Thursday that showed demand for rough diamonds is continuing to plunge as polishers and traders refuse to buy stones when they can’t make a profit.
The mining company holds 10 sales events each year in Botswana, where its chosen buyers — known in the industry as sightholders — are given a box containing plastic bags filled with diamonds. In the past three sales, De Beers made less than $300 million, which is unprecedented in data going back to 2016.
