What diamond colours are the rarest?

Diamond wedding and engagement rings traditionally have a white or colourless centre stone. It’s the indicator that the piece is classified under bridal jewellery.

But did you know that diamonds have other colours? They occur due to several factors that affect one another such as pressure, temperature and elements.

Although, not all colours are readily available everywhere. Some colours are more common than others while a select few rarely occur.

Learn about the other colours of diamonds and the rarest occurring ones.

Green

Green diamonds are included in the list of limited fancy colours.

The 41-carat Dresden Green is the largest natural green diamond. What makes it exceptional is its colour being constantly distributed throughout its body.

The colour in green diamonds is mostly caused by natural radiation. It is rare for the colour to reach the deepest parts within a diamond.

Blue

Diamonds get this colour because of the presence of boron, a naturally-occurring element created by supernovae and cosmic ray spallation.

The first recorded blue diamond was the Hope Diamond from India back in the 17th century.

Aside from India, blue diamonds have been found in South Africa and Australia as well.

According to sources, blue and pink compete for the title of being the second rarest diamond colour.

Red

Of all diamond colours, red is the rarest.

Red diamonds are created only from carbon. The colour is created by a deformation in their structure called ‘plastic deformation’.

The colour of these diamonds can range from dark pink to purplish red which is almost magenta in appearance.

Diamonds with stronger red hues have a higher value than the ones that don’t.

To further prove the rarity of red diamonds, the Gemological Institute of America (GIA) records reveal that there wasn’t one that was registered between the year 1957 and 1987.
