Petra Diamonds Struggles as Rough Diamond Prices Keep Falling

Gems News: Ongoing Weakness in the Diamond Market

Petra Diamonds has reported another challenging quarter as global rough diamond prices continue to tumble. Despite a rise in total revenue to $52 million for the first fiscal quarter ending September 30, the miner revealed that this growth came from a higher sales volume rather than improved market conditions. The average price per carat fell by 13% to $110, signaling sustained pressure on the industry as demand remains subdued. In contrast, Petra had conducted two tenders this quarter compared to none during the same period last year, after merging its delayed September 2024 sale with October’s event.

Shifting Product Mix Amid Declining Prices

According to this Gems News report, Petra’s revenue boost was largely attributed to a better-quality product mix, primarily from the Cullinan mine in South Africa, instead of a rebound in prices. Quarter-on-quarter comparisons show a 53% improvement in average price, but when adjusted on a like-for-like basis, prices still slipped by 8%. The miner is banking on new access points at its Finsch mine to enhance output quality, hoping to stabilize performance amid the downturn.

Debt Pressure and Reduced Output

Petra’s financial position remains tight, with its $102 million revolving credit facility fully drawn and net debt increasing to $287 million from $264 million at the end of June. Production also dropped by 10% year-on-year to 609,336 carats, partly due to the sale of its Williamson mine in Tanzania earlier in 2025. The company’s inventory rose to 468,733 carats valued at $44 million, up from 328,689 carats worth $30 million at the end of June.

Bleak Outlook for the Diamond Industry

The ongoing decline in rough diamond prices reflects broader global market weakness driven by sluggish consumer spending, synthetic diamond competition, and shifting luxury trends. Unless a rebound occurs in global jewelry demand, miners like Petra may face further financial strain and restructuring pressures in 2025. The company’s future depends heavily on market recovery and operational improvements at its key mines.
