Argyle Pink Diamond Buying Guide
Colour, Source & Quality
Pink Diamonds have always been exceedingly rare. In the 16th and 17th centuries, India was the principal source of Pink Diamonds. Today, it is the Argyle Pink Diamond mine in Western Australia that is the most consistent producer of rare natural Pink Diamonds. Currently Argyle’s production contributes 90% of the world’s total Pink Diamond supply. In spite of newly established underground operations, the mine’s life expectancy is very short and experts predict that by 2018 the Argyle mine will be fully exhausted. The extreme scarcity of Pink Diamonds has meant that only a privileged few have owned them in the past. It is this scarcity, coupled with their extreme beauty that has made them 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: 1P is an intense pink, with graduations in colour through to Pink, Purplish Pink, Pink Rosé, Pink Champagne and Blue Violet.
The GIA (Gemological Insitute 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 color of the diamond, such as Red, Pink, Blue or Yellow. The Tone, or secondary color, 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 colors are virtually equal within the diamond.
Ultimately, the color grade of a Pink Diamond is the primary key to its value, before cut, clarity and carat.
