Pink Argyle diamonds mined from Australia’s Argyle mine has always been the craze for diamond investors but the situation has changed now.
For a while, rumors were out there that the Argyle mine will close its doors and now that has become the reality as the mine is now defunct since it has exhausted all of its natural resources.
This means the already rare pink diamond is now rarer as no new pieces are being extracted let alone pushed into the global market. The result of this event is that the price of Argyle’s pink diamonds is skyrocketing along with the demand for them.
Is there any reason that drives the craze for this particular diamond variant?
Sure there are!
Here are three of them –
The composition of pink-colored diamonds
As per experts, pink-colored diamonds from Argyle mine have a unique composition. It is because these diamonds are formed in the Argyle volcanic pipe which is made up of olivine lamproite.
When the volcano exploded, chemical interactions between normal diamond pieces with minerals such as Mica, Kaolinite, and Zeolite led to the development of molecular defects in the diamonds.
On top of this, when the diamonds were subjected to enormous tectonic temperatures and pressure, it led to the scenario where the aforementioned impurities stuck with the molecular structure of the diamonds. This further led to the fact that they are now able to exhibit pink hues when subjected to white light.
The colour variations of pink-colored diamonds
Pink diamonds from Australia’s Argyle mine come in various types.
They are classified as follows –
- Purplish Pink (PP)
- Bubble Gum Pink (BCP)
- Pink Rosé (PR)
- Pink (P)
- Pink Champagne (PC)
Apart from classifying them as per their pink hues, these diamonds are again segregated based on the intensity of the pink hues they exhibit. This is done using a grading system that comes with a range between one and nine. One is considered as the highest and nine is considered as the lowest.
The rarity of pink-coloured diamonds
More than 90% of the world’s pink diamond supply came from the Argyle diamond mine of Australia.
This is not the only reason why these diamonds are considered ‘rare’. The main reason is when two and a half million ore extracted from the mine were processed by the Argyle mine, only one pink-coloured diamond was found.
Furthermore, as mentioned earlier, the supply for this particular diamond variant was already limited, to begin with. Now, since the mine is closed, supply has come to a halt and the world is only left with the pieces that are already in the lockers of private owners and showcases of collectors.
Hence, the price of pink Argyle diamonds has already started to shoot up.

Furthermore, you should only buy certified pink-coloured diamonds else, you won’t be able to sell the piece or pieces at the market price when you finally choose to part with them.
