Argyle Diamonds Over 90% of all natural fancy pink diamonds are found in the Argyle Diamond Mine, located in the East Kimberly region of Western Australia. The Anglo-Australian mining giant, Rio Tinto Limited, began mining the region in 1982. They quickly became the world’s most reliable source for natural pink diamonds.


Since through open pit mining the goods extracted from the ground have almost entirely depleted, in order to obtain the amounts necessary, extensive excavation beyond 2000 meters is required. The shortage of pink diamonds is consistently increasing and exactly what results to expect from deep excavation is still unknown.

Through the years these diamonds have significantly grown in popularity and demand. However, the Argyle diamond mine already estimated only ten years of supply remains through open pit mining until diamonds will no longer be produced from that site, and that was in the year 2009!

Argyle Pink Diamond Tender One of the most popular marketing campaigns the Argyle Diamond Mine has been running for quite some time is the Argyle Pink Diamond Tender. Results from the past few tenders prove the fact that the quality of the diamonds found is consistently dropping, thus making them more valuable.

The graphs below demonstrate the difference between the years 2011, 2010, 2009 and 2001

Clarity: Argyle Pink Diamond Tender, Clarity Chart The following chart demonstrates clearly how the clarity grades have decreased over time. For example, in 2001, stones with the clarity grade I1 represented only 20% of all the stones tendered. While in 2011, stones with the clarity grade I1 represented a strong 36% of the 55 stones tendered.


Intensity: Argyle Pink Diamond Tender, Intensity Chart The following chart clearly shows the difference shown in color intensity over time. For example, in 2001, 59% of the stones were Fancy Deep and 22% were Fancy Intense while in 2011 only 5% were Fancy Deep and 76% were Fancy Intense. This shows the decrease in strong colors from the argyle tender over the years.


Carat Weight: Argyle Pink Diamond Tender, Carat Weight Chart The following chart depicts the sizes of the argyle tender stones and shows how they are getting smaller and smaller due to the lack of goods. In 2001, 39% of the stones were 1.00ct – 1.99ct, 27% were 0.75ct – 0.99ct, and 27% were 0.50ct – 0.47ct. In 2011, only 31% of the stones were 1.00ct – 1.99ct, 15% were 0.75ct – 0.99ct, and 40% were 0.50ct – 0.74ct. Also, it really is quite amazing that this year’s Argyle Pink Diamond Tender had two stones of 0.30ct. That is very small considering the mines top output over the past year.
