Diamonds

Diamonds are precious gemstones composed of crystallised carbon and one of the most valuable natural commodities traded globally. They form deep within the Earth's mantle under extreme pressure and temperature conditions, typically brought to the surface through volcanic eruptions in kimberlite or lamproite pipes. The diamond industry encompasses exploration, mining, cutting, polishing and retail distribution, with applications spanning jewellery, industrial cutting tools and advanced technology components. Major diamond-producing regions include southern Africa, Russia, Canada and Australia, with Botswana, Russia and Canada ranking among the world's largest producers by value. The gemstone market is dominated by natural diamonds graded on the four Cs: carat weight, cut, clarity and colour, though laboratory-grown diamonds have gained market share in recent years. Diamond mining operations range from large-scale openpit and underground mines operated by multinational corporations to artisanal and small-scale mining in alluvial deposits. The sector is subject to certification schemes such as the Kimberley Process, designed to prevent conflict diamonds from entering the legitimate trade. Diamonds remain a critical export commodity for several African economies, particularly Botswana, South Africa, Namibia and Angola, where the industry contributes significantly to government revenues and employment. Prices are influenced by global economic conditions, consumer demand in key markets such as the United States, China and India, and supply dynamics controlled by major producers and trading centres in Antwerp, Dubai and Mumbai. The industry has faced challenges including price volatility, competition from synthetic alternatives and evolving consumer preferences towards ethical sourcing and sustainability.

World Diamond Council sets deadline for revised System of Warranties

The World Diamond Council says the transition period to its revised System of Warranties concludes on September 21, after which the revised declaration becomes the sole reference within its framework for all diamond transactions, including rough, polished and jewellery. The mechanism, which extends the Kimberley Process Certification Scheme, requires companies to declare on invoices that diamonds originate from legitimate sources; executive director Elodie Daguzan says the 2021 revision incorporates broader due-diligence principles covering human rights, anti-corruption and anti-money-laundering, and urges companies to align documentation before the deadline.

Natural diamond industry under strain from lab-grown competition and demand decline

Diamond industry expert Avi Krawitz says demand for natural diamonds has stagnated in China and the US over the past three years, with global production falling in 2025 and expected to decline again this year. The Natural Diamond Council has appointed new CEO Amber Pepper and secured increased funding from members including Angola and Botswana, while De Beers promotes its Origin Diamonds traceability brand to build consumer confidence.

Angola and Congo push transparency and value addition

Angola became Africa's second-largest diamond producer by value in 2024, at $1.41-billion, and has bid for a 20% to 30% stake in De Beers. The Democratic Republic of Congo has signed a deal with Switzerland's ADEX Platform to build a cutting and jewellery facility and digital sales platform, aiming to curb smuggling as output fell to 8.1-million carats in 2025.
