Natural diamond production is highly concentrated. Only a handful of countries have rich diamond mines. The whole industry is controlled by several large mining corporations around the world. Let’s take a look at the top natural diamond producing countries first.
Russia
It is the world’s biggest natural diamond producer. It leads the globe in both total carat output and total value of rough diamonds. Alrosa is its leading company, and it is also one of the largest diamond mining firms across the world. Most famous mines locate in the Sakha Republic, also known as Yakutia, in Siberia. Udachny and Mir are two world-class diamond pits here. They supply huge amounts of rough diamonds every year.
Botswana
Botswana ranks among the most important diamond nations by value. Diamond business is the main pillar of its national economy. The major operator here is Debswana, a joint venture work with De Beers. Jwaneng and Orapa are its core mining areas. People call Jwaneng the richest diamond mine on Earth. It keeps bringing high-value rough diamonds year after year.
Canada
Canada is well-known for high-end natural diamonds. Its diamonds are widely recognized as ethical sourced. Two big names run the local mines: Rio Tinto and De Beers. Major mines including Diavik, Ekati and Gahcho Kué sit in the Northwest Territories and Nunavut. Canadian diamonds always win good reputation in global luxury jewelry market.
Democratic Republic of the Congo
This country produces a large volume of diamonds by carat weight. But most of its output are small stones. Many are low-grade gem diamonds or just for industrial use. You need to pay extra attention here. Some diamonds from this area may still link to conflict diamonds. The Kimberley Process is made to stop this bad situation, but buyers should still be careful when choosing diamonds from this region.
Australia
Australia was once one of the top diamond producers. It was famous for stunning pink diamonds. The Argyle Mine was its most iconic site. Unluckily, Argyle closed down in 2020. No new pink diamonds from this mine will come out again. For this reason, Argyle pink diamonds become extremely rare, and their price jump sharply. Today, Australia’s total diamond output has dropped a lot.
Other notable natural diamond producing countries include Angola, South Africa and Namibia. They also play a part in global rough diamond supply.
Different from natural diamonds, lab-grown diamonds rely on modern technology and manufacturing. Production is spread among major tech and manufacturing hubs worldwide. Below are the key regions for lab-grown diamonds.
China
China is the world’s largest maker of lab-grown diamonds, especially HPHT diamonds. It owns the largest number of HPHT presses globally. With advanced equipment, factories here can produce small and medium carat diamonds efficiently at low cost. Henan province is the absolute industrial center. Cities like Zhengzhou and Shangqiu take up a huge share of global HPHT diamond production.
India
India has long been the top center for diamond cutting and trading. Now it also grows fast in CVD diamond production. Cities such as Surat have massive processing bases and skilled workers. They can easily move their traditional diamond processing knowladge to lab-grown diamonds, like cutting and polishing. Many local companies keep building more CVD reactors to expand production scale.
United States
The US is a leader in technology research and development. It is also an important player in the high-end lab-grown diamond market. There are many famous lab diamond brands here, such as Diamond Foundry and WD Lab Grown Diamonds. These companies mainly use CVD method. They focus on making large carat, top-quality lab diamonds, and put lots of effort on brand building and marketing.
Singapore, Europe and Russia also have companies developing and making lab-grown diamonds. However, their production scale is much smaller compared with China and India.
Now let’s compare natural diamonds and lab-grown diamonds clearly.
In terms of industry nature, natural diamond belongs to resource mining industry. Lab-grown diamond is high-tech manufacturing.
The core elements are totally different. Natural diamonds need mine resources and mining rights. Lab-grown diamonds depend on technology, capital, energy and complete supply chains.
Main producing areas also vary. Natural diamonds mainly come from Russia, Botswana, Canada and other mining countries. Lab-grown diamonds are concentrated in manufacturing hubs: China for HPHT, India and the US for CVD production and tech brands.
Both kinds of diamonds can get standard grading certificates. Common labs include GIA, IGI, AGS and more. There is no big difference on mainstream certification choices.
When it comes to operating companies, natural diamond industry is ruled by giant mining groups like De Beers and Alrosa. Lab-grown diamonds are produced and sold by tech firms and manufacturing enterprises.
All in all, natural diamonds and lab-grown diamonds come from two totally different industrial systems. They have different production models, cost structures and market positioning. Understanding these differences will help you make better choices when buying diamonds.
