Pink diamonds are rare in the world market. More than ninety per cent of pink diamonds come from the world-famous Argyle diamond mine in Australia. Now, since the mine is on its way to permanent closure in the year 2020, people from all over the globe can’t help but wonder what makes Argyle pink diamonds so valuable and interesting. To begin with, less than one per cent of Argyle total output is pink diamonds.
This makes the pink diamonds very rare when one compares its numbers with other coloured diamonds. If you are making a rough estimate, if the Argyle mine is churning out 1 million carats of diamonds in their natural form then only one carat of the lot will be a pink diamond!

The results are pink diamonds that reflect incoming light in a different way compared to white diamonds that gives them their signature pink hue.
They are high in terms of market value
