Tanzania’s Williamson Diamonds goes totally Pink

London-listed and South Africa-active Petra Diamonds has sold its entire shareholding in Williamson Diamonds of Tanzania, plus all shareholder loans owed to it, to Pink Diamonds Investments, also of Tanzania.

Pink diamonds are known for their pink hue, ranging from light to deep rose.

The up-to-$16-million transaction has obtained Tanzanian Fair Competition Commission approval for Williamson ownership now vesting entirely with Pink, a Taifa affiliate, which is viewed as possessing the technical and financial capability to conduct operations for the benefit of stakeholders.

With more than three decades of mining-related experience, Taifa’s working relationships extend to mining majors such as De Beers, Barrick and AngloGold Ashanti, and the company is now entering a phase of exclusive ownership of an asset where about 1 100 people are employed, most of them Tanzanian.

The mine’s reserves and resources as of June 30 were reported as 37.17-million carats. With liquidity challenges continuing, further capital investment will be required.

Twenty per cent of any distributable cash generated annually by Williamson will be payable by Pink Diamonds to Petra until the selling price is met, Petra joint interim CEO Vivek Gadodia outlined in a release to Mining Weekly, in which he wished Pink all of the best as its takes over the mine, the kimberlite pipe of which was discovered by Canadian geologist John Williamson in 1940 and which led to ongoing operation since then, making it one of the world’s oldest continuous operating diamond mines. Its yield of 19-million-plus diamond carats includes a 54.5 ct Williamson pink diamond that was presented to British royalty in 1947.

Meanwhile, Petra, with the Cullinan and Finsch underground diamond mines in South Africa, is focusing on value rather than volume at a time when diamond-mining headwinds are tending to dominate the headlines and the usual sale of rough diamonds at acceptable prices is reportedly proving difficult.

This has resulted in the stockpile of rough diamonds held by De Beers, for example, rising to $2-billion, which, according to a report in the Financial Times, is the biggest hold back of rough diamonds since the financial crisis of 2008.

Petra Diamonds delays sale amid US tariffs uncertainty

Africa-focused Petra Diamonds has postponed a scheduled sale of about 200,000 carats of diamonds from its Cullinan mine in South Africa, citing uncertainty over the impact of new US tariffs.

Last week, US President Donald Trump announced sweeping import tariffs ranging from 10% to over 100%, including a 30% duty on many South African goods. The move has injected volatility into the global diamond market.

Petra, which holds the world’s third-largest diamond resource, said the decision to delay the Cullinan sale aims to secure stronger market prices once the tariff situation becomes clearer. The sale had been expected to generate approximately $18 million in revenue.

Despite the disruption, the company managed to complete sales from its Finsch mine in South Africa and the Williamson mine in Tanzania before the tariffs were introduced.

South Africa remains one of the largest diamond exporters to the US, alongside India.

So far in the 2025 financial year, Petra has earned $103 million from rough diamond sales, down from $138 million during the first five tenders of the previous year.

Petra’s entire interest in Williamson headed for Tanzania’s Pink Diamonds

An agreement has been entered into for the outright sale of Williamson Diamonds Limited, Petra Diamonds announced on Wednesday.

The London-listed and South Africa-active Petra is taking steps to sell its entire shareholding in the Tanzanian entity to Pink Diamonds Investments for a headline consideration of up to $16-million.

This follows Petra’s sale in May of just under half of the asset, in which the Tanzanian government has a stake, for $15-million via long-term technical services contractor Taifa Mining.

Since then, Williamson’s coming under consolidated ownership has emerged increasingly as the preferred way forward.

As a Taifa affiliate, Pink Diamonds is viewed by Petra CEO Richard Duffy as possessing the technical and financial capability to conduct operations in a responsible manner for all stakeholders.

As a wholly Tanzanian-owned company with more than three decades of mining-related experience, Taifa’s working relationships extend to mining majors such as De Beers, Barrick and AngloGold Ashanti. It is now entering a phase of exclusive ownership of the asset where about 1 100 people are employed, most of them Tanzanian.

The mine’s reserves and resources as of June 30 were reported as 37.17-million carats. With liquidity challenges continuing, further capital investment will be required.

“We look forward to working closely with the Mining Commission, the Fair Competition Commission, employees, community representatives and other key stakeholders in completing the sale as soon as possible,” Duffy stated in a stock exchange announcement accessed by Mining Weekly.

In South Africa, Petra operates the Cullinan diamond mine in Gauteng and the Finsch diamond mine in the Northern Cape.

“We’re committed to adopting and adhering to the latest internationally recognised standards throughout all aspects of our business,” said Pink Diamonds chairperson Rostam Azizi, whose family are from the area around Mwadui, the other name for the Williamson mine, which is situated 23 km north-east of Shinyanga in northern Tanzania.

Mining Weekly can report that the discovery of the kimberlite pipe by Canadian geologist John Williamson in 1940 led to ongoing operation since then, making it one of the world’s oldest continuous operating diamond mines. Its yield of 19-million-plus diamond carats includes the 54.5 ct Williamson pink diamond presented to British royalty in 1947.
