More Than a Precious Metal: How Platinum Improves Our World

How Platinum Improves Our World

Within the hierarchy of precious metals, there is only one metal that could arguably stand above gold, and that is platinum.

This is due in large part to the metal’s rarity throughout history. Its earliest known use was on the Casket of Thebes in Ancient Egypt. South American Indigenous populations also used platinum for jewelry.

But platinum’s value goes beyond being a precious metal—its specific properties have made it indispensable to the modern economy, improving both the health and the wealth of the world.

Platinum’s Industrial Applications

Today’s infographic comes to us from the World Platinum Investment Council and outlines specifically how specific platinum’s properties are used in the modern economy.

There are four primary uses of platinum aside from investment demand.

  1. Manufacturing
  2. Healthcare
  3. Environmental
  4. Renewable Power

Let’s look into all of these cases a little deeper.

1. Manufacturing

Platinum’s versatility in manufacturing has quadrupled its demand since 1980. Its catalytic properties are critical to the production of fertilizers, and more specifically, platinum’s efficiency in converting ammonia to nitric acid paved the way for large-scale fertilizer production.

Around 90% of the nitrogen produced using platinum catalysts is used to make 190 million tonnes of fertilizers each year.

2. Healthcare

Platinum is a biologically compatible metal because it is both non-toxic and stable. It does not react negatively with or affect body tissues, which makes it an ideal material for medical tools. Platinum’s use in medicine dates back to 1874 for its use in arthroscopic tools. Its stability also makes it ideal for pacemakers and hearing assist devices today.

While non-threatening to healthy cells, platinum compounds known as cisplatin can damage cancer cells and treat testicular, ovarian, lung, bladder, and other cancers. Given these crucial applications, the World Health Organization has put cisplatin on its List of Essential Medicines.

3. Environmental

Platinum is a critical material in the fight for cleaner air and in the construction of energy-efficient fiberglass. It is used in catalytic converters in exhaust systems of gas-powered vehicles, reducing the emission of harmful pollutants. In addition, platinum is used in the manufacturing process of high-end glass that improves the heating and cooling efficiency of homes and offices.

4. Renewable Power

Platinum’s catalytic properties make it critical to cleaning up air pollution, producing renewable hydrogen, and unleashing its power in fuel cells. Electrolysis, which can turn water into hydrogen and oxygen, works best when passing an electric current through platinum electrodes.

Fuel cells are set to power a new generation of emission-free vehicles, and platinum membranes are used inside of them as well.

More Than Precious

More than a precious metal, platinum has many applications that make it a critical material for the modern economy in years to come.

Ranked: The World’s Top Diamond Mining Countries, by Carats and Value

Who are the leaders in rough diamond production and how much is their diamond output worth?

A cropped chart showing the leaders in rough diamond mining and how much their diamond output is worth.

Ranked: World Diamond Mining By Country, Carat, and Value

Only 22 countries in the world engage in rough diamond production—also known as uncut, raw or natural diamonds—mining for them from deposits within their territories.

This chart, by Sam Parker illustrates the leaders in rough diamond production by weight and value. It uses data from Kimberly Process (an international certification organization) along with estimates by Dr. Ashok Damarupurshad, a precious metals and diamond specialist in South Africa.

Rough Diamond Production, By Weight

Russia takes the top spot as the world’s largest rough diamond producer, mining close to 42 million carats in 2022, well ahead of its peers.

ℹ️ Carat is the unit of measurement for the physical weight of diamonds. One carat equals 0.200 grams, which means it takes over 2,265 carats to equal 1 pound.

Russia’s large lead over second-place Botswana (24.8 million carats) and third-ranked Canada (16.2 million carats) indicates that the country’s diamond production is circumventing sanctions due to the difficulties in tracing a diamond’s origin.

Here’s a quick breakdown of rough diamond production in the world.

Note: South Africa’s figures are estimated.

As with most other resources, (oil, gold, uranium), rough diamond production is distributed unequally. The top 10 rough diamond producing countries by weight account for 99.2% of all rough diamonds mined in 2022.

Diamond Mining, by Country

However, higher carat mined doesn’t necessarily mean better value for the diamond. Other factors like the cut, color, and clarity also influence a diamond’s value.

Here’s a quick breakdown of diamond production by value (USD) in 2022.

21🇻🇪 Venezuela$0.10M
22🇲🇱 Mali$0.06M
Total$16,290M

Note: South Africa’s figures are estimated. Furthermore, numbers have been rounded and may not sum to the total.

Thus, even though Botswana only produced 59% of Russia’s diamond weight in 2022, it had a trade value of nearly $5 billion, approximately 1.5 times higher than Russia’s for the same year.

Another example is Angola, which is ranked 6th in diamond production, but 3rd in diamond value.

Both countries (as well as South Africa, Canada, and Namibia) produce gem-quality rough diamonds versus countries like Russia and the DRC whose diamonds are produced mainly for industrial use.

Which Regions Produce the Most Diamonds in 2022?

Unsurprisingly, Africa is the largest rough diamond producing region, accounting for 51% of output by weight, and 66% by value.

RankRegionShare of Rough
Diamond Production (%)
Share of Rough
Diamond Value (%)
1Africa51.4%66.4%
2Europe34.9%32.9%
3North America13.5%52.8%
4South America0.2%2.4%

However diamond mining in Africa is a relatively recent phenomenon, fewer than 200 years old. Diamonds had been discovered—and prized—as far back as 2,000 years ago in India, later on spreading west to Egyptian pharaohs and the Roman Empire.

By the start of the 20th century, diamond production on a large scale took off: first in South Africa, and decades later in other African countries. In fact between 1889–1959, Africa produced 98% of the world’s diamonds.

And in the latter half of the 20th century, the term blood diamond evolved from diamonds mined in African conflict zones used to finance insurgency or crime.
