Without this supply from the Australian Argyle diamond mine, it’ll be hard to see even a fraction of pink diamond introduced to the market annually. The rare characteristics of Argyle pink diamonds, coupled with the mine’s closure, make any Argyle diamond tacked with its name (which has become a brand in itself) valuable.

What is the origin of Argyle diamonds?

How rare are Argyle pink diamonds in Australia?

How rare are Argyle pink diamonds? Since opening in 1983, the Australian Argyle mine has supplied the world with more than 865 million carats of natural diamond material. But only 5% of that are gem-quality (the rest are industrial-grade). Of that 5%, 80% of the diamonds are a variation of a brown diamond, 15% are yellow hues, 4% are colourless, and 1% are pink, red, blue, and violet diamonds. The diamonds account for some of the most valuable diamonds on earth, and they’re so rare that a year’s worth of the diamonds can fit in the palm of your hand. Moreover, pink diamonds, specifically, only account for less than 1% of the world’s gemstone production.

What gives pink Argyle diamonds their natural colour?

The rare colour of Argyle pink diamonds is attributed to the Argyle pipe, a volcanic pipe made of olivine lamproite. Due to an eruption, minerals interacted with the diamonds causing distortions in their crystal structure, giving them their natural pink hue. Pink diamonds add style and sparkle to any piece of diamond jewellery, including rings, earrings, bracelets, and more. You could get a loose pink diamond to set in any personal piece of jewellery.
