The Story Behind Fancy-Coloured Diamonds

Welcome to the 2nd part of our series which explores all 12 fancy-coloured diamonds.

In our previous article: Fancy Coloured Diamond Guide - Blue, Red, Brown and Green., we explored the mysterious world of blue and red diamonds. 

Their stories border on legend and people are prepared to pay fantastic amounts to get their hands on these precious stones.

Topping the rarity scale was red and blue. Their hues can spark an instant feeling within us which explains the hefty price tags they come with!

In this guide, you'll read the story behind:

  • Yellow diamonds.
  • Black diamonds.
  • White diamonds.
  • Grey diamonds.

For every 10,000 diamonds found, only one is classified as a fancy-coloured stone. However, that one stone could be one of 12! 

Yellow Diamonds

After brown, next up on the common scale are yellow fancy-coloured diamonds. 

After being exposed to nitrogen, the diamond develops a yellow colour which ranges from a light colour to an intense and vibrant hue with the latter being hard to find. 

As with most diamonds, they have their own colour scale. With yellow, it ranges from light to dark. 

Trivia - A yellow diamond can have a secondary colour such as brown or orange. 

Black Diamonds

The demand for diamonds of this hue only became apparent in the late 90s. They are essentially small crystals stuck together. This means they are one of the most durable of all fancy-coloured diamonds.

It must be noted that black diamonds can be treated so it's important to get as much information as you can if you want to buy one. 

When a diamond is treated, their colour will be artificially changed by replicating the conditions they were formed in. For example, exposing the stone to high temperatures and pressure. 

Trivia - There is only one grade for these diamonds, Fancy Black.

It's believed that traces of graphite found in the structure during the diamond's formation is the reason behind its colour. 

White Diamonds

Yes, these are real! 

They are a milky/snow-like colour but opaque in nature. 

Their story is interesting. So, the reason behind their colour can be found in the submicroscopic inclusions which disperses light and this results in the snowy colour you see. 

Trivia - submicroscopic inclusions is still a grey area and the jury is still out but right now? It's leaning towards the presence of nitrogen in the diamond's structure.

They are difficult to find and similar to fancy black-coloured diamonds, they have one colour grade, Fancy White.

Grey Diamonds

Grey diamonds are quite unique because of the story behind their formation. They can be formed in two different ways!

Saturation to boron or hydrogen is said to be the reasons behind their colour.

Grey-fancy coloured diamonds are subject to a wide colour scale ranging from light to deep and the diamond itself can contain a secondary colour such as blue which creates a stunning finish!

Final Words

The unusual cases behind the grey fancy-coloured diamond illustrate their strange nature. 

Fancy-coloured diamonds will continue to be a mystery for all of us but it doesn't stop us going deeper into their underlying features.
