From the Depths of the Earth to the Pinnacle of Luxury.

Each Argyle Pink Diamond™ is timeless. A story that began more than one and a half billion years ago, and one that will live on for generations to come.



Argyle pink diamonds offer a vibrancy and spectrum of colour not seen in other diamonds, which contribute to their revered reputation for rarity, beauty and luxury. It is well known that when buying any diamond, it’s advisable to look for the four Cs – colour, clarity, cut and carat.

This also applies when buying a pink diamond, with the exception that there is a greater focus on colour, as the intensity or rarity of colour elevates a pink diamond’s value. The ultimate pink diamond is not necessarily large, in fact only a very small percentage are more than a carat.

The Gemological Institute of America grades pink diamonds by both colour and clarity, with colour categories ranging from Faint Pink through to rare colours such as Fancy Deep Pink and Fancy Red


For fancy coloured diamonds, the ‘C’ for colour typically outweighs the other three Cs (clarity, cut and carat weight) in determination of value. This certainly applies to Argyle pink diamonds, as the value commonly increases along with the intensity of colour. While clarity and the presence of fluorescence may ordinarily impact the value of white diamonds, these characteristics are less of a consideration in the value determination of Argyle pink diamonds.


When global financial markets show volatility and instability, affluent collectors around the world continue to seek out true rarity and diversify into hard assets. Much like fine art and antiques, Argyle pink diamonds fulfil these criteria, and as supply dwindles, international collectors continue to acquire these rare pieces for their personal holdings.

Parallels are often made with Argyle pink diamonds and fine art – not only because each polished stone is in itself a work of art, but due to the allure and perpetual value associated with both. Historically fine art and Argyle pink diamonds have sustained their worth and each maintained their status as a definitive collectable, regardless of market conditions.



From the moment a rough Argyle pink diamond is unearthed from the Argyle Diamond Mine until the time it is offered for purchase as a polished stone, the collectable is upheld by professional vigilance and dedicated care.

Once unearthed, each Argyle pink diamond over eight points (0.08cts) was authenticated with documentation and a unique lot number laser inscribed on the gem, visible only under magnification.
