This September, famed mining and resource company Rio Tinto will be holding it’s 30th annual Argyle Diamond Tender.   This year’s event is shaping up to be one of the most memorable in history as a trio of color diamonds will be taking centre stage.

The star of the tender, this radiant cut, 1.21 carat, Fancy Red diamond is named after the red North American bird.   Some industry experts believe this stone could break the “per-carat” record of $1.6 million for a Fancy Red diamond.

The Argyle Toki


This Fancy Intense Purplish-Pink emerald cut diamond weighs in at 1.59 carats.

Rio Tinto’s annual Argyle Diamond tender is always one of the most important events of the calendar year for jewel enthusiasts.   Over 90% of the world’s pink diamonds come from this mine.   The expected closing date for the mine is around 2018-2019 so these commodities will only increase in value in the coming years.

Overall, this year’s Rio Tinto tender will feature 55 color diamonds, 4 of which will be Fancy Red. In the tender’s 30 year history, there has only been 13 Fancy Red diamonds made available so this year’s crop is expected to garner some huge returns for the company.
