Did you know2024
De Beers owns Element Six, the world's largest producer of synthetic industrial diamonds and the dominant supplier of quantum-grade CVD diamonds used in quantum sensing and computing. Diamond's NV (nitrogen-vacancy) centers are the premier solid-state qubit candidate for room-temperature quantum sensing. De Beers/Element Six supply quantum-grade diamonds to government defense labs, quantum computing startups, and research institutes globally. The global luxury diamond cartel is therefore a critical materials supplier for US and European quantum technology programs — a fact absent from virtually every quantum technology supply chain risk assessment.

Following Western sanctions on Russia after the February 2022 invasion of Ukraine, Alrosa (~30% of global rough diamond supply) was cut off from G7 direct sales. The G7's January 2024 ban on Russian diamonds (enforced via Antwerp diamond exchange origin verification) bifurcated the global diamond market: De Beers (Western-origin) vs. Alrosa-rerouted stones through UAE/India. De Beers' share of G7-accessible rough diamond supply is now estimated at 45–50%, effectively restoring partial cartel-era market power in Western markets without any formal agreement.

De Beers operated arguably the most successful and longest-running legal cartel in industrial history. From 1934 to 2001, through its Central Selling Organisation (CSO) in London, De Beers controlled 75–85% of global rough diamond distribution — artificially inflating prices for 67 years. The US DOJ indicted De Beers for price-fixing in 1994, barring it from US operations for a decade. In 2004, De Beers pleaded guilty to price-fixing and paid a $10 million fine — one of the smallest criminal antitrust fines relative to the duration and scale of the cartel. The "A Diamond Is Forever" campaign (1947) was widely credited with engineering the cultural association between diamonds and marriage proposals, sustaining cartel-level demand.
