In the small world of coloured diamonds, red diamonds are the rarest of all. An extremely small proportion of all the diamonds in the world are graded as Fancy Red. Most of these fall in the category of tiny diamond pieces that are below one carat. Because of this, the 2.11-carat red diamond unveiled in New York in the last week of July 2017 as a part of the Argyle Pink Diamonds Tender, is even more extraordinary.
Named as Argyle Everglow, the 2.11 carat fancy red diamond is the largest red diamond in the 33-year history of the Argyle Pink Diamonds Tender. The Argyle Pink Diamonds Tender showcases top-quality pink diamonds that emerge from the Rio Tinto Argyle diamond mine in Western Australia. The 2.11-carat Argyle Everglow red diamond is the largest such diamond in the tender’s history.
This diamond has been polished into a radiant-cut with a VS2 clarity stamp by the GIA. The stone is likely to drive global demand from collectors.
The red and pink coloured diamonds get their colour as the result of an atomic deformity, which effects the way light is refracted through the stone. Only 0.03% of the diamonds mined every year are pink, and an even smaller proportion of these are red.
The largest known red diamond is Moussaieff Red, a 5.11-carat red diamond discovered in the 1990s by a Brazilian farmer. This diamond was sold to the Moussaieff jewellery house.
