To say that natural red diamonds are extremely rare is akin to saying that you have a small chance of winning the lottery twice in a row”
Eden Rachminov, The Fancy Color Diamond Book – 2009.
Red diamonds are the rarest diamonds in the world, this is a simple fact. What is a lesser known fact, is that not all Red diamonds are the same colour.
Most red diamonds on the planet are not a pure red and have what is known as a “modifying” colour, such as purple or brown. Of the few red diamonds which appear truly RED, the largest in the world is only just over 5 carats.
Compare this with the world’s largest Brown (400+cts), Yellow (230+cts), Pink (180+cts), Blue (45+cts) and Green (41+cts) diamonds and it becomes even clearer how rare red diamonds are. Of all the world’s red diamonds, it is generally accepted that the most stunning and vibrant reds come from the Argyle diamond mine in Australia. These red diamonds are usually offered for sale by invitation only, to the partners and diamond associates of Argyle - such as Mondial Pink Diamond Atelier - through the exclusive Argyle Pink Diamonds Signature Tender.
As of 2018, there have been 34 annual Signature Tenders held, with an average of only 1 GIA certified “Natural Fancy Red” diamond per Tender! Most natural coloured diamonds are faceted into shapes other than round; such as emerald cut, radiant, oval and pear shapes. Round brilliant cut red diamonds are the rarest of the rare and it is estimated that there are less than 30 of them in the world, the majority being Argyle Tender diamonds sold in the last 5 years. With only 1 or 2 more Tenders expected before the mine closure, the world’s main source of Red diamonds is about to cease production and natural red diamonds will become rarer than ever.
