About Natural Fancy Coloured Diamonds


Naturally coloured diamonds are extremely rare and are a natural occurrence. When someone talks about a “fancy diamond” they do not mean a diamond that is discoloured as this relates impurities that cause a white diamond to look dirty and yellow. A fancy diamond is typically more vivid in colour and only 1 out of approximately 10,000 carats of diamonds are coloured. 

Coloured diamonds are formed when foreign particles impact the crystallization process and depending on what this particle is the colour changes. A coloured diamond range can come in pink, red, purple, blue, green, yellow, orange and champagne. The most common of these are yellow diamonds.

Yellow Diamonds

Often referred to as “canary” diamonds, the yellow diamond is one of the most popular diamonds for engagement rings. The yellow comes from nitrogen which entered the diamond during the crystallization process. This caused blue light to be absorbed which gives the diamond it’s luminous yellow colour. 

Pink Diamonds

Pink diamonds are increasing in popularity for engagement rings. The intense pink colour was made by the pressure and heat during the formation process which caused the stone to absorb green light. Australia, particularly the Kimberley region, is known as a source of pink diamonds but this is a finite source. 

Brown Diamonds

Like pink diamonds, brown diamonds were made when green light was absorbed by the stone. Brown diamonds are increasingly being used as a unique centre stone of engagement rings but until the 1800’s they were only thought good for industrial use as it was an unpopular colour. They are found primarily in Australia and are coined “champagne diamonds”. 


Green Diamonds

Green diamonds are slowly making an impact on people but are rarer than yellow, pink and brown diamonds, which make them more expensive. The colour is made from the stone being exposed to radiation near the earth’s crust. It then absorbs red and yellow light which produces the unique hue. It is typically matched with pink diamonds. 

Purple Diamonds

These types of diamonds are very rare and are extremely expensive. Only a very few have ever been mined in Australia. Scientists believe that the colour is due to lattice distortion and the presence of hydrogen in the stone. It is not commonly used in engagement rings due to its scarcity, but it would look incredible.

Blue and Blue-Grey Diamonds

This is a very rare gemstone, similar to the violet diamonds but slightly more accessible. These are being used in engagement rings more often in recent times. The stone is blue due to the presence of the Boron particle which makes the stone absorb red, green and yellow light. The strength of blue varies and the more vivid blue is more popular for engagement rings, but the blue-grey stones can appear quite grey and not very blue.
