According to Allied Market Research, in 2022, the global diamond market was valued at $100.4 billion, with projections indicating an increase to $155.5 billion by 2032. This forecast suggests a compound annual growth rate (CAGR) of 4.5% from 2023 to 2032. Similarly, the market value for lab-grown diamonds worldwide stood at $22.3 billion in 2021. It is expected to expand to $55.6 billion by 2031, exhibiting a CAGR of 9.8% from 2022 to 2031, also per Allied Market Research.

The market for lab-grown diamonds is undergoing significant growth, propelled by advancements in production technology and evolving consumer values. As these diamonds are generally 30-40% less costly than naturally mined diamonds, they hold considerable appeal for cost-conscious consumers. A 2021 report from MVI Marketing revealed that approximately 70% of millennials would consider a lab-grown diamond for an engagement ring, indicating a shift in generational attitudes.

But despite this, the allure of natural diamonds persists, deeply rooted in tradition and bolstered by the marketing heft of industry giants. According to a study by De Beers, a subsidiary of Anglo American Plc (LSE:AAL.L), natural diamonds continue to possess a profound emotional and aspirational charm, with many consumers viewing them as inherently valuable and prestigious. Therefore, despite the rising popularity of lab-grown stones, the top diamond producing countries are likely to maintain a profitable position in the market.

Ban On Russian Diamonds in the Talks 

Discussions are underway about a potential ban on Russian diamonds, with reports indicating that the G7 countries are considering prohibiting the import of Russian diamonds into their markets. Four proposals on this matter have been put forward — by Belgium, India, a French gem trade company, and the World Diamond Council. India, despite being unwilling to abandon its over half-a-century-old ally, also seems to agree to the ban terms. Notably, the sanction’s terms are currently under review, though the schedule for a decision remains uncertain.

Such a ban could have a significant impact on Russia’s diamond exports, as the G7 nations — comprising the US, Canada, Japan, Germany, the UK, Italy, and France — make up approximately 70% of the world’s diamond purchases. The potential embargo could disrupt the supply chain, given Russia’s status among the major diamond producing countries and its 30% share in the global market.

For the ban to be effective, there must be a consensus on the definition of diamond traceability to ensure the origins of diamonds can be verified. The primary points of contention among the proposed strategies are the criteria for entry of diamonds into G7 markets, the methods for verifying their Russian origin, and the ramifications for failing to comply with the established regulations.

Recent updates indicate that Belgium and India are lobbying for diamonds to be routed through their respective trading centers in Antwerp and Mumbai, aiming to preserve their leading roles. In contrast, the World Diamond Council is recommending a less stringent, self-regulatory approach, while the French company is advocating multiple entry points for Russian stones to enter the big markets.

The World Diamond Council has announced that leaders from numerous jewelry and gemstone associations have voiced their support for the G7 Diamond Protocol at the 2023 CIBJO (World Jewelry Confederation) Congress’s inaugural session. This endorsement is likely to strengthen the initiatives to limit the import and trade of rough and polished diamonds originating from Russia.

The United States has already sanctioned Alrosa, the Russian state-owned diamond company. However, the sanction’s impact is limited without a worldwide embargo. Notably, the esteemed jeweler Tiffany & Co. has also stopped sourcing diamonds from Russia and has instructed its suppliers to separate Russian diamonds from those from other sources to avoid purchasing Russia’s stones. 

De Beers, owned by Anglo America plc (LSE:AAL.L) is a leading competitor of Alrosa and endorses the World Diamond Council’s proposal but emphasizes the importance of involving other top diamond producing countries to amplify the ban’s effect.

Reaching a consensus on the embargo is challenging due to the potential economic repercussions it could have on prominent diamond trading centers such as Belgium, India, or the US. Therefore, although the details of when and how the ban will be implemented remain unclear, it is evident that excluding a significant player like Russia from the market will lead to supply chain disruptions.

Developments in Diamond Mining 

Diamonds are rare and valuable, and unlike bulk commodities that are traded on open markets, they are sold through a more controlled supply chain. For instance, De Beers, a subsidiary of Anglo American plc (LSE:AAL.L), has historically stockpiled diamonds to regulate market supply. The company maintained market stability by purchasing diamonds from other producers and withholding them from the market, thus ensuring a limited supply.

Consequently, this strategy helped keep prices stable and high, even amidst fluctuating demand. When demand declined, De Beers would constrict supply further by releasing fewer diamonds. In contrast, when demand increased, the company would release more from its reserves. This market influence was feasible because De Beers once commanded between 80-90% of the rough diamond market share.

However, De Beers’ control over the diamond supply chain has become more flexible, with companies like Rio Tinto Group (NYSE:RIO) expanding their presence. A significant 2021 development saw Rio Tinto Group (NYSE:RIO) become the sole proprietor of the Diavik Diamond Mine in Canada’s Northwest Territories, thereby asserting a dominant position in the Canadian diamond market. According to Rio Tinto Group (NYSE:RIO), the Diavik mine’s output in Q2 2023 was approximately 970,000 carats of diamonds, a decrease from the 1.1 million carats in Q2 2022 but an increase from 954,000 carats in Q1 2023. The mine produced a total of 4.7 million carats in 2022, with the reduced yield attributable to the ongoing underground pipe construction.

In another significant development, Debswana Diamond Company Ltd., a joint venture between the Botswana government and De Beers Group, launched the first-ever 5G-ready smart diamond mine at its Jwaneng site, utilizing Huawei’s innovative mine solution in December 2021. This system, replacing an outdated one with limited range and poor interference resistance, operates on a 4G eLTE private network. It ensures stable, real-time data transmission between mining vehicles and equipment. This innovation is a foundation for subsequent 5G upgrades to facilitate high-speed, low-latency technologies such as autonomous vehicles, propelling the mining industry toward a more digitally intelligent future. Further developments like this could allow leading diamond producing countries to benefit more from their minerals.

Historically overshadowed by its extensive gold reserves, Brazil’s diamond industry has experienced a resurgence due to the discovery of new kimberlite pipes in the state of Minas Gerais. Brazilian diamonds are sourced from primary deposits, such as kimberlite pipes, and secondary deposits in riverbeds where alluvial mining is prevalent. The country’s diamond exports peaked at $59 million in 2017 and currently stand at $26 million, according to the Kimberley Process. 

14. Guinea

Average Annual Diamond Production: 0.210 million carats

In Guinea, diamond extraction is primarily alluvial, with deposits spread across the country’s interior regions. Despite political instability and governance challenges, diamonds remain a vital component of the mineral economy. Like many other major diamond producing countries, Guinea’s diamond industry experienced consistent growth in the past decade but has recently decelerated. Guinea’s diamond exports currently stand at $8 million, down from $66 million in 2008. A significant portion of diamonds is smuggled out of the country and, consequently, is not officially recorded as exports. Consequently, the country’s export volume remains constrained despite sufficient production levels.

13. Tanzania

Average Annual Diamond Production: 0.274 million carats

The diamond industry in Tanzania centers around the Mwadui mine and benefits from a geological context that supports primary and alluvial deposits. There has been a transformation in the industry as the government takes a more active oversight role, aiming for equitable distribution of financial benefits. According to the Kimberley Process, diamond exports brought in approximately $74 million in 2019 and $81 million in 2018, with a slight decrease to $63.1 million in subsequent years.

12. Liberia
