How are Pink Diamonds Formed?


Pink diamonds are one of the rarest colours of diamond available. Very few people will ever get the chance to hold a pink diamond let alone of one of exceptional size and colour. 

The majority of pink diamonds are found in Western Australia’s Kimberly region, in particular the Argyle mine. Diamonds in this area were initially found as alluvial diamonds, meaning they were quite literally found in the riverbed and probably still are. 

How the pink or red in a diamond is formed is actually not completely known. What is known however is that these particular diamonds are lacking a complete chemical structure and it is actually a flaw and combination of stress that creates the colour. Unlike other diamonds where the colour is a trace element, eg. Nitrogen for yellow diamonds, Boron for blue diamonds, Uranium for green…

Because of this ‘flaw’ if you will call it, the diamond actually becomes slightly weaker and is much more prone to flaws in the diamond. That’s why when we are looking at pink diamonds, especially from the Argyle region, we are not especially concerned with the clarity, we are simply looking at the diamond for it’s intense colour, which is most important. This is also the reason that it is incredibly hard to find a pink diamond over 1ct, and especially rare to see a pure red diamond of any size!

These diamonds, as with any other, are a gift from nature and cannot simply be ‘made to order’, but we can try our best. If you would like to see these diamonds it is best to make an appointment.
