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.

Visualized: The EV Mineral Shortage

Demand for mineral supply of lithium, nickel, and cobalt is expected to grow from 10%-20% to over 80% by 2030.

How Mineral Supply Will Change EV Forecasts

Did you know that EVs need up to six times more minerals than conventional cars?

EVs are mineral-intensive and are pushing up demand for critical battery metals. According to the International Energy Agency (IEA), lithium, nickel, and cobalt demand is expected to grow from 10%-20% to over 80% by 2030.

As countries around the world pledge to go all-electric by 2035 and 2040, do we have enough mineral supply for EV demand?

Factors such as geopolitical concentration of resources, quality of materials, mining industry lead times, and environmental factors will together determine whether we have the minerals we need.

Let’s take a look at how critical minerals are affected.

MineralConstraints
CopperCopper mines currently in operation are nearing their peak, suffering from reserve exhaustion, while ore quality in older mines is declining.

South American and Australian mines are located in areas where water availability can be scarce.
This could cause setbacks given the high water requirements needed for the mining process.
NickelThere are a number of growing concerns related to higher CO2 emissions and waste disposal.

Nickel quality needs to be high (Class 1) for EV batteries. Most nickel in the global supply chain is unusable for EVs.
CobaltThe Democratic Republic of Congo and China account for around 70% of production.

90% of cobalt produced is a by-product of nickel and copper, making new supply subject to the development of these mines.
Rare Earth Elements Concerns surrounding negative environmental credentials in processing operations.

The value chain from mining to processing and magnet production is geographically concentrated in China.
LithiumThe world could face severe lithium shortages as early as 2025.

Lithium mines that started operations between 2010-2019 took an average of 16.5 years to develop.

China accounts for 60% of global production and more than 80% of lithium hydroxide.

Over 50% of lithium mines are located in areas that suffer water shortages.
This could cause setbacks, given the high water requirements for mining processes.

Recycling is a partial solution to alleviate critical mineral supply but will fall short of meeting the high levels of demand until around the 2030s.

The EV Supply Chain

Currently, the resources for EV batteries are concentrated in very few countries. This concentration is an increasing concern for supply chain distribution.

China is home to more than half of the world’s lithium, cobalt, and graphite processing and refining capacity, as well as three-quarters of all lithium-ion battery production capacity.

Europe accounts for more than one-quarter of worldwide EV assembly, but home to very little of the supply chain, with the region’s cobalt processing share accounting for 20% of the mix.

Meanwhile, both Korea and Japan control a sizable portion of the downstream supply chain after raw material processing. Korea accounts for 15% of worldwide cathode material production capacity. Japan produces 14% of cathode and 11% of anode material.

The United States accounts for just 10% of EV production and 7% of battery production capacity.

Suggested Solutions

To reduce setbacks surrounding resource demand, KGP Auto’s new report recommends that material supply is accessed and matched to a broader fuel energy mix.

In this scenario, platinum group metals (PGMs) continue to play a leading role in the auto industry by assisting in building cleaner emission vehicles.

These vehicles support more sustainable fuels such as hydrogen, filling the gaps to net-zero targets by allowing EVs to catch up with material supply
