Petra shutters Finsch mine, cuts jobs as diamond slump bites

Petra Diamonds (LON: PDL) is placing its Finsch mine into business rescue and cutting jobs across its South African operations as collapsing diamond prices and strong rand threaten the miner’s liquidity and future.

The company said Friday that worsening conditions in the natural diamond market, compounded by Middle East tensions and weaker prices for smaller stones, have forced it to take emergency measures. 

Finsch’s average realized price fell to about $47 per carat in April and May from $56 per carat in the third quarter, while prices at Petra’s flagship Cullinan mine dropped to roughly $81 per carat from $109 per carat. 

Petra said Finsch, which generated 34% of group revenue in fiscal 2025 and primarily produces diamonds of two carats and below, has been hit by what management described as a structural decline in prices for smaller stones.

The company has suspended capital development at Finsch, redirected equipment to support production and launched consultations that could lead to workforce reductions across the group. Petra, which employs more than 4,000 people, did not disclose how many jobs could be affected but said it had begun a consultation process with employees and unions.

“We are faced with an unprecedentedly weak diamond market, due to global macro factors as well as the recent Middle East tensions,” CEO Vivek Gadodia said. “We believe that there is now a structural shift on pricing of smaller sized diamonds and therefore do not foresee a significant price appreciation for the smaller sized diamonds.”

The company also halted production guidance for fiscal 2026 through 2030 pending a revised business plan expected by the end of September.

Industry shift

The restructuring highlights mounting pressure across the diamond sector as slowing Chinese luxury demand and the growing popularity of lab-grown stones weigh on prices. Producers have responded by curtailing operations, reducing inventories and reassessing expansion plans. 

Petra’s decision to place Finsch into business rescue underscores concerns that lower-value diamonds may face a prolonged decline in demand and pricing.

Cullinan remains central to Petra’s future strategy because of its ability to produce rare, high-value Type II diamonds that command premium prices. The company is increasing mining in areas known to host those stones and is testing productivity improvements aimed at boosting recoveries and throughput. 

Liquidity focus

To support the restructuring, Petra secured lender consent to ensure the Finsch business rescue process does not trigger defaults under its senior bank facilities or second-lien notes. 

The company also warned it could breach minimum liquidity requirements later this year, prompting discussions with creditors and a formal bondholder consent process.

Investors reacted sharply to the announcement. Petra shares fell 17% in early afternoon trading to 11p, extending their decline to more than 30% this year. The company’s market capitalization has shrunk to about £42 million ($56 million).

The overhaul will bring leadership changes as well. Joint CEO Operations Juan Kemp will leave the company at the end of May following a mutual separation agreement with the board. Gadodia will become sole chief executive and join the board as Petra focuses on preserving liquidity and reshaping the business around Cullinan’s higher-value production.
