10 Biggest Diamond Companies in the World

In this piece, we will take a look at the ten biggest diamond companies in the world. For more companies, head on over to 5 Biggest Diamond Companies in the World

Diamonds are among the most precious and rarest minerals on Earth. Their rarity is due to the fact that it takes thousands of years for a piece of coal, once subjected to mind boggling pressures (thought to be 45,000 times the pressure at sea level), to turn into a diamond. They are found both under the land and under the sea, and since they were carried to their destination through molten rock, each diamond in existence today is more than 100 million years old. As if this were not enough, on average, it takes miners to sift a whopping 250 tons of Earth to find a single carat of diamonds.

Mining diamonds from under the sea requires using specialized crawlers to suck up the seabed, which is then searched for diamonds. Therefore, it is clear that the harder the process of extracting a diamond, the higher its price will be. The industry itself is worth hundreds of billions of dollars. Or at least that is what the research firm The Business Research Company would have you believe. According to its estimates, the global diamond market was worth $504 billion in 2021, and by the end of this year, it will have grown by a compounded annual growth rate (CAGR) of 9.5% and sit at $552 billion. From then until 2026, the industry will grow at a much slower 4.6% CAGR and be worth $661 billion by the end of the forecast period. The demand for diamonds is expected to grow due to the rising affluence of India and China, as populations in the growing economic powers see their disposable incomes rise.

Moving towards the diamond mining industry, the global diamond reserves stood at 1.4 billion carats as of January 2021, according to Global Data. While production declined in 2020 due to the coronavirus pandemic, it was expected to grow once again last year and stand at 113 million carats in 2021. Between 2021 and 2025, production is expected to grow at a CAGR of 2% or higher. As is the case with nearly every industry, the diamond mining sector has also started to utilize technology for its operations. A new technology that is currently being used by companies is X-Ray Transmission (XRT) technology. This allows both land and sea miners to determine the quality of their haul, as they beam x-rays on each stone to determine the amount that is absorbed or reflected.

Russia is the world’s largest diamond supplier, as it accounted for one third or 31% of the global diamond production in 2020. Finally, the global market for lab grown diamonds is highly evolving. This particular segment was worth $19.3 billion in 2020, and it will grow at a CAGR of 9.4% until 2030 to sit at $50 billion. Lab grown diamonds have a variety of use cases, especially since diamonds in general are also among the hardest objects on Earth. Some traditional use cases involve cutting and mining, while the relatively newer ones include usage in electronics, optics, and lasers.

As you can likely infer, the diamond industry is blossoming, and today’s piece will look at some of the largest firms in the industry. Out of these, the top players are Public Joint Stock Company ALROSA (MCX:ALRS.ME), Rio Tinto Group (ASX:RIO.AX), and Anglo American plc (LSE:AAL.L).

AI, Tariffs, Nuclear Power: One Undervalued Stock Connects ALL the Dots (Before It Explodes!)

Artificial intelligence is the greatest investment opportunity of our lifetime. The time to invest in groundbreaking AI is now, and this stock is a steal!

AI is eating the world—and the machines behind it are ravenous.

Each ChatGPT query, each model update, each robotic breakthrough consumes massive amounts of energy. In fact, AI is already pushing global power grids to the brink.

Wall Street is pouring hundreds of billions into artificial intelligence—training smarter chatbots, automating industries, and building the digital future. But there’s one urgent question few are asking:

Where will all of that energy come from?

AI is the most electricity-hungry technology ever invented. Each data center powering large language models like ChatGPT consumes as much energy as a small city. And it’s about to get worse.

Even Sam Altman, the founder of OpenAI, issued a stark warning:

“The future of AI depends on an energy breakthrough.”

Elon Musk was even more blunt:

“AI will run out of electricity by next year.”

As the world chases faster, smarter machines, a hidden crisis is emerging behind the scenes. Power grids are strained. Electricity prices are rising. Utilities are scrambling to expand capacity.

And that’s where the real opportunity lies…

One little-known company—almost entirely overlooked by most AI investors—could be the ultimate backdoor play. It’s not a chipmaker. It’s not a cloud platform. But it might be the most important AI stock in the US owns critical energy infrastructure assets positioned to feed the coming AI energy spike.

As demand from AI data centers explodes, this company is gearing up to profit from the most valuable commodity in the digital age: electricity.

The “Toll Booth” Operator of the AI Energy Boom

  • It owns critical nuclear energy infrastructure assets, positioning it at the heart of America’s next-generation power strategy.
  • It’s one of the only global companies capable of executing large-scale, complex EPC (engineering, procurement, and construction) projects across oil, gas, renewable fuels, and industrial infrastructure.
  • It plays a pivotal role in U.S. LNG exportation—a sector about to explode under President Trump’s renewed “America First” energy doctrine.

Trump has made it clear: Europe and U.S. allies must buy American LNG.

And our company sits in the toll booth—collecting fees on every drop exported.

But that’s not all…

As Trump’s proposed tariffs push American manufacturers to bring their operations back home, this company will be first in line to rebuild, retrofit, and reengineer those facilities.

AI. Energy. Tariffs. Onshoring. This One Company Ties It All Together.

While the world is distracted by flashy AI tickers, a few smart investors are quietly scooping up shares of the one company powering it all from behind the scenes.

AI needs energy. Energy needs infrastructure.

And infrastructure needs a builder with experience, scale, and execution.

This company has its finger in every pie—and Wall Street is just starting to notice.

Wall Street is noticing this company also because it is quietly riding all of these tailwinds—without the sky-high valuation.

While most energy and utility firms are buried under mountains of debt and coughing up hefty interest payments just to appease bondholders…

This company is completely debt-free.

In fact, it’s sitting on a war chest of cash—equal to nearly one-third of its entire market cap.

It also owns a huge equity stake in another red-hot AI play, giving investors indirect exposure to multiple AI growth engines without paying a premium.

And here’s what the smart money has started whispering…

The Hedge Fund Secret That’s Starting to Leak Out

This stock is so off-the-radar, so absurdly undervalued, that some of the most secretive hedge fund managers in the world have begun pitching it at closed-door investment summits.

They’re sharing it quietly, away from the cameras, to rooms full of ultra-wealthy clients.

Why? Because excluding cash and investments, this company is trading at less than 7 times earnings.

And that’s for a business tied to:

  • The AI infrastructure supercycle
  • The onshoring boom driven by Trump-era tariffs
  • A surge in U.S. LNG exports
  • And a unique footprint in nuclear energy—the future of clean, reliable power

You simply won’t find another AI and energy stock this cheap… with this much upside.

This isn’t a hype stock. It’s not riding on hope.

It’s delivering real cash flows, owns critical infrastructure, and holds stakes in other major growth stories.

This is your chance to get in before the rockets take off!

Disruption is the New Name of the Game: Let’s face it, complacency breeds stagnation.

AI is the ultimate disruptor, and it’s shaking the foundations of traditional industries.

The companies that embrace AI will thrive, while the dinosaurs clinging to outdated methods will be left in the dust.

As an investor, you want to be on the side of the winners, and AI is the winning ticket.

The Talent Pool is Overflowing: The world’s brightest minds are flocking to AI.

From computer scientists to mathematicians, the next generation of innovators is pouring its energy into this field.

This influx of talent guarantees a constant stream of groundbreaking ideas and rapid advancements.

By investing in AI, you’re essentially backing the future.

The future is powered by artificial intelligence, and the time to invest is NOW.

Don’t be a spectator in this technological revolution.

Dive into the AI gold rush and watch your portfolio soar alongside the brightest minds of our generation.

This isn’t just about making money – it’s about being part of the future.
