Selecting a Pink Diamond

Pink Diamonds have always been exceedingly rare. The Argyle Pink Diamond mine in Western Australia provided 90 per cent of the world’s rare natural Pink Diamonds, yet only 0.1% of the total mine’s production was pink. As the Argyle Diamond mine is now closed, Pink Diamonds are rarer than ever before.

Colour, Source and Quality

The extreme scarcity of Pink Diamonds means that owning one is the privilege of a lifetime. It is this scarcity, coupled with their extreme beauty that has made Argyle Pink Diamonds the most desired and most valuable Diamond around the world.

Argyle Pink Diamonds are unique to the point that a dedicated grading system has been specifically developed by Argyle. The colours are graded from one being the most intense and vivid colour graduating through to nine, a soft blush of pink. Argyle is famous for producing an incredibly rare range of coloured diamonds including Purplish Pink, Pink, Pink Rosé and Pink Champagne. Even more rare are the elusive Red, Purplish Red and Blue Violet diamonds.

The GIA (Gemmological Institute of America) lists their grading scale by three elements of saturation, hue and tone. Saturation is based on the quality of colour, such as Vivid or Intense. Hue is the main colour of the diamond, such as Red, Pink, Blue or Yellow. The tone, or secondary colour, if any, precedes the hue and is expressed as an adjective with “ish”, such as Purplish Pink. Altogether, a complete GIA name might be Vivid Purplish Pink Diamond. A grade with two nouns like Pink Rose indicates the two colours are virtually equal within the diamond. Ultimately, the color grade of an Argyle Pink Diamond is the primary key to its value, before cut, clarity and carat.
