The different colours of diamonds arise from differences in the atomic structure. The difference in atomic structure has to do with impurities in the diamond: another naturally occurring element is compressed along with the carbon.
- If boron were present when forming, the result will be a grey or blue diamond.
- The presence of nitrogen produces a yellow diamond.
- Diamonds get a purple colour in the presence of high levels of hydrogen.
- A distorted crystal lattice can result in pink, red or brown diamonds.
- Green diamonds are colourless until they rise almost to the earth's surface. There, they are exposed to natural radiation. The diamonds absorb this radiation and so turn green.
- There is some doubt about black diamonds, but their colour is probably influenced by graphite.
The way they are formed sees to it that every coloured diamond is unique. Every coloured diamond has its own hue. As a result, they are generally more valuable than colourless ones.
Blue diamonds come in all different shades. The Hope Diamond is one of the most well-known blue diamonds.
Sapphires are a lovely alternative to expensive blue diamonds, like the one set into this necklace here.
Because their colour makes the diamond sparkle less than a colourless one, brown diamonds are less expensive than other coloured diamonds.
The most well-known yellow diamond is the Tiffany Yellow Diamond. It is one of the largest there is, and among other things, Audrey Hepburn wore it in a necklace on the Breakfast at Tiffany’s film set.
The Moussaiëff Red Diamond is the largest and most expensive red diamond, at 13.9 carats.
Rubies are a fine alternative to red diamonds, which are extremely rare.
The most famous pink diamond is the Pink Star. At no less than 59.6 carats, this gemstone is valued at more than €67 million.
Pink diamonds are a lovely alternative to a colourless diamond in, for example, an engagement ring.
Black diamonds are very popular with men, set into a wedding ring, for example. The black colour means these diamonds do not sparkle as much, making them look trendier.
The most famous black diamond is the Black Amsterdam Diamond.
The most famous purple diamond is the Royal Purple Heart. At 7.34 carats and I1 clarity, it is the largest diamond of its kind.
One of the most famous green diamonds is the Aurora Green Diamond. The 5.03 carat diamond is set in a halo ring with pink diamonds.
Emeralds are an alternative to green diamonds. Since coloured diamonds are so scarce, they are also very valuable. Emeralds can be a more economical choice here.
Large pink and blue diamonds continued to do especially well, attracting the highest bids. One highlight was certainly the sale of the Pink Star at Sotheby’s.
The price of coloured diamonds
It can be said of colourless diamonds: the paler the colour, the more expensive they are, because the rarer and more sought after they are. Diamonds with a fancy colour are valued differently. If a colour is rare, such as red, the reasoning goes: the more intense the colour, the more it is worth.
The more intense the colour, the more it is worth
The popularity and price of coloured diamonds have been on the rise worldwide for some time, due to their rarity, but also thanks to Asian investors. According to the Fancy Color Research Foundation (FCRF) - the not-for-profit coloured diamond index - coloured diamonds appreciated in value by an average of 157.4% from 2006 to 2014. By comparison, asking prices for colourless diamonds increased "only" 62.4% in the same period.
