The World of Coloured Diamonds

Quality diamonds with size, brilliance, and clarity are hard to find as it is. Add in colouration, which can occur mainly because of structural anomalies in the diamond crystal or certain impurities, and that diamond is even rarer.

It turns out the vast majority of diamonds (98.1%) are classified as Type 1 and have nitrogen as an impurity. This can make them white, yellow or brown in colour. The rest are classified as Type 2, and these make up the category of “more desired” coloured diamonds.

Structural anomalies can make these diamonds yellow, brown, orange, pink, red, or purple in colour. A small amount instead have boron as an impurity, which can make the diamonds blue or grey. Green diamonds can also occur if a diamond of another colour is exposed to radiation in a certain way.

Many hard assets investors consider things such as rare coins, paintings, or coloured diamonds as another way to preserve wealth. The rarity and uniqueness of these assets make them something special. While not fungible or a medium of exchange like something such as pure gold or silver, they do tend to hold their value over time. Things such as coloured diamonds also are extremely portable, which gives them a the advantage of wealth mobility over cash or other bullion.

Despite efforts from the U.S. and EU to secure local domestic supply, all major EV battery manufacturers remain based in Asia.

In this graphic we rank the top 10 EV battery manufacturers by total battery deployment (measured in megawatt-hours) in 2023. The data is from EV Volumes.

Chinese Dominance

Contemporary Amperex Technology Co. Limited (CATL) has swiftly risen in less than a decade to claim the title of the largest global battery group.

The Chinese company now has a 34% share of the market and supplies batteries to a range of made-in-China vehicles, including the Tesla Model Y, SAIC’s MG4/Mulan, and various Li Auto models.

Company	Country	2023 Production (megawatt-hour)	Share of Total Production
CATL	🇨🇳 China	242,700	34%
BYD	🇨🇳 China	115,917	16%
LG Energy Solution	🇰🇷 Korea	108,487	15%
Panasonic	🇯🇵 Japan	56,560	8%
SK On	🇰🇷 Korea	40,711	6%
Samsung SDI	🇰🇷 Korea	35,703	5%
CALB	🇨🇳 China	23,493	3%
Farasis Energy	🇨🇳 China	16,527	2%
Envision AESC	🇨🇳 China	8,342	1%
Sunwoda	🇨🇳 China	6,979	1%
Other	-	56,040	8%

In 2023, BYD surpassed LG Energy Solution to claim second place. This was driven by demand from its own models and growth in third-party deals, including providing batteries for the made-in-Germany Tesla Model Y, Toyota bZ3, Changan UNI-V, Venucia V-Online, as well as several Haval and FAW models.

The top three battery makers (CATL, BYD, LG) collectively account for two-thirds (66%) of total battery deployment.

Once a leader in the EV battery business, Panasonic now holds the fourth position with an 8% market share, down from 9% last year. With its main client, Tesla, now sourcing batteries from multiple suppliers, the Japanese battery maker seems to be losing its competitive edge in the industry.

Overall, the global EV battery market size is projected to grow from $49 billion in 2022 to $98 billion by 2029, according to Fortune Business Insights.
