and Red Diamond Grading

Argyle certified Red and Purplish Red diamonds are estimated to be 25 times rarer than a GIA certified red diamond and are considered the rarest of all reds! On average there are twice as many Argyle Reds as Argyle Purplish Reds. The main difference with an Argyle certified red diamond is they don’t contain any negative secondary Brown, Grey or Orange over tones, as can be found in GIA graded red diamonds with no Argyle certification. This characteristic gives an Argyle certified Red / Purplish Red diamond the title of the world’s purest Red and Purplish Red saturation, along with the statistics that there have only ever been 49 Red and 30 Purplish Red diamonds with a total caret weight of 50.83ct in the 30-year history of the Argyle.

GIA certified Purplish Red and Red Diamond Grading

Fancy colour diamonds are found in twelve different colours, but with over 230 colour combinations from various locations around the globe. All coloured diamonds are classified by the GIA into several intensity grades, Very Light, Light, Fancy Light, Fancy, Fancy Intense, Fancy Deep and Fancy Vivid. The only exception is a Fancy Red or the rarer Fancy Purplish Red that come in only one intensity grade; Fancy Red / Purplish Red. Like many other colour diamonds, most GIA certified Fancy red diamonds can be found with slight secondary hues, which include purple, brown, grey and orange. For the GIA to grade a diamond red, the diamond must display a dominate deep reddish tone with flashes of pure red. As long as the secondary colour is only slight, it will not be added to the GIA report giving the diamond a straight Fancy red grade. The unreported secondary colour tones such as brown, grey and orange can have a dramatic negative affect on the look and price of a red diamond. Whereas, the rarer secondary purple tone can increase the look and value of the red diamond.
