The diamond market is going through a major crisis, marked by a prolonged drop in demand, due in particular to the growing popularity of synthetic diamonds. This has led to a significant fall in prices. Several corroborating sources say prices have fallen by over 25% since 2022.

The trend is reflected in the average export price from the Democratic Republic of Congo (DRC). According to official data, it has fallen from $12.5 per carat in 2022 to $9.6 in 2024, a drop of 23.2%.

This situation further complicates the recovery of Société minière de Bakwanga (Miba), which has been in difficulty for over twenty years. The turnaround strategy is based on the potential of the polygon, Miba's historic concession, which still harbors significant diamond deposits.

On April 8, Miba CEO André Kabanda introduced four South African companies- Bond Equipment, Mining Services, Athur Mining, and Consulmet-"interested" in working together to revive the business. These companies are due to submit bids for the supply of modern equipment after visiting the mining infrastructure and sites. However, the continuing fall in prices could dampen investor enthusiasm.

Conditions for a Relaunch

Appointed Chairman of the Board in November 2023, Jean-Charles Okoto undertook a tour of Europe in late 2024 to attract new partners. On this occasion, ASA Resource, a 20% shareholder, pledged to invest $50 million in the relaunch. To date, however, it remains unclear whether this contribution has been made.

While Miba's ambition was to produce 12 million carats by 2025, its activities remain suspended.

Miba's situation reflects that of the sector as a whole. Since 2017, recorded national production has fallen from 17.9 million to 9.2 million carats in 2024.

"Relaunching the sector requires structural reforms to enhance transparency, support artisanal mining, attract industrial investment, and ensure that diamond wealth truly benefits local populations," argues IPIS, a research organization based in Antwerp, in a report published on April 23, 2025.

According to the USGS, the DRC holds around 150 million carats, or 9% of the world's known industrial-grade diamond reserves.
