Everyone knows the classic, colourless diamond. The yellow and pink diamond are familiar to most people too, but did you know there are brown, green, blue and even black diamonds? The black diamonds are rather special, because they are fully opaque, contrary to all other colours. What makes black diamonds so special and when are they interesting to invest in?

What are black diamonds?

Large black diamonds of a good cut quality can be very valuable. However, they will always remain more affordable than most other coloured diamonds, because they sparkle a lot less. Instead of reflecting the light, they absorb it. Which is not to say they cannot be set into beautiful diamond jewellery.

Natural black diamonds are only found in very few diamond mines. Only a few mines in Brazil and Central Africa are known to supply black diamonds.

According to some, black diamonds come from much deeper in the earth than other diamonds and they are created between 140 and 190 kilometres below the surface. This especially high pressure and the temperatures at those depths would give them their unique colour. Others posit that they can be found all over the planet and that these unique gems found their way to Earth inside an asteroid.

What is the difference between black diamonds and colourless diamonds?

Black diamonds and colourless diamonds very similar. The specific process that gives black diamonds their unique opaque colour is not fully known. As stated above, some think they come from space. There are many different hypotheses regarding the creation of the natural black diamond, but there is no agreement. The theory that has the most support worldwide is that the black colour is caused by the presence of graphite in the crystal structure during the formation of the diamond.

Such graphite inclusions are not present in colourless diamonds. That is the only difference in qualities between colourless and black diamonds.

Why should I go for black investment diamonds?

Pink, red and blue diamonds are still seen as the best investment diamonds. Their extreme rarity pays off faster and bigger than other colours. But they are more difficult to sell in comparison to white diamonds, due to their high value. Coloured diamonds are also more popular than black diamonds due to their brighter shine. The lack of shine is a large drawback for the black diamond.

In other words, black diamond is only a good investment if the gem is reasonably large or has a characteristic property that can create a big demand on the market, such as a special cut form or a truly unique hue within the black spectrum.

Natural unprocessed black diamonds are found in a lower price category than other coloured diamonds. The purchase price for 1.00 ct. will be around €3,000 and €5,000, which makes investing in diamond much more accessible if you are inexperienced in investing in diamond.
