What are blue diamonds and why are they so special?

Blue diamonds are 100% natural diamonds that come in various shades of blue, ranging from light blues and greenish blues to dark blue and blue with a purple tinge. Blue diamonds are not colourless ones treated to achieve a blue colour, but ones that are naturally coloured blue.

As with other coloured diamonds, this colouring is brought about by the presence of a chemical, in this case, the chemical element boron. However, the blue colouring should not be confused with the gemstone sapphire, which is a variety of the mineral corundum.

Blue diamonds are only found in a few mines in the world, the most important of which is the Cullinan mine in South Africa. They were also mined at the Argyle mine in Australia, the largest producer of pink diamonds, which was recently closed down due to depleted resources.

How much does it cost to buy blue diamonds?

Although coloured diamonds are actually a combination of pure diamond with an impurity in the form of a chemical, they are still considerably more expensive than colourless diamonds with a high clarity. This is partly due to the fact that coloured diamonds are extremely rare, and partly because demand for these coloured varieties is increasing.

This trend can also be seen with blue diamonds. They are mined in a very limited number of sites and are, therefore, very scarce. This makes them popular with collectors and private buyers. This is especially the case when it comes to blue diamonds with an intense blue colouring. Other hues such as light blue and darker varieties are also popular. However, their value could be affected if the blue is too light or too dark. The colour and colour intensity of coloured diamonds are recorded accurately on diamond certificates from a reliable laboratory such as GIA, IGI or HRD, using a scale ranging from "faint" to "fancy vivid".

Along with the colour and its intensity, clarity is another important element for determining the value and price of blue diamonds. Clear diamonds are the most valuable of all. Ultimately, the number and type of inclusions determines the clarity score for blue diamonds. Beyond this, the carat weight and cut quality and shape also influence their value and price.

The price of blue diamonds, therefore, depends on the value of the diamond, but also on the economic climate and the diamond dealer from where you purchase it. The average price of a 0.5-carat light blue diamond is USD 26,280. However, you pay a lot more for deep blue diamonds, which could reach an average of USD 75,000 for 0.25 carats.

Why invest in blue diamonds?

Investing in blue diamonds can be a profitable business if you have considered it carefully. Unlike colourless diamonds, which have huge commercial appeal, these colourful gems are a niche market and are often traded through specialist auction houses. To get the most from investing in blue diamonds, you should seek advice from an expert such as the specialists at BNT Diamonds.

Investing in blue diamonds can be profitable in the long term, due to their scarcity. The scarcity of these diamonds has only increased over the years, which led to a significant increase in demand but with limited supply.

Are you looking to buy blue diamonds or blue sapphires?

Coloured gemstones have risen in popularity in recent years and this trend is also seeing an increase in demand for coloured diamonds or other high-quality coloured gemstones.

However, the price of blue diamonds may be out-of-reach for some investors. Especially if you don’t have a huge budget. Investing in blue sapphires can be a good alternative. Blue sapphires fall into a lower price bracket and are often chosen as an investment. Nonetheless blue sapphires are not as secure investments as diamonds and, therefore, could be considered as a high-risk investment. You can read more about the pros and cons of this type of investment, in our blog post on investing in blue sapphires or blue diamonds.
