Pink Diamonds

The fascinating origin of the natural pink diamond’s colour is largely a mystery and the subject of ongoing debate. Unlike other coloured diamonds where the colour is the result of a trace element, pink diamonds are not the result of an impurity. Rather, they are thought to obtain their colour as a result of extreme pressure beneath the earth’s surface.

Western Australia’s Argyle Pink Diamonds date back more than 1 billion years. It is understood that the crystal lattice was altered by geological forces to produce a unique structure that absorbs light in such a way that the gemstone assumes a stunning pink hue.

For coloured diamonds, the ‘C’ for colour outweighs the other Cs (cut, clarity, and carat weight) in determining the value. Consequently, it pays to understand how colour affects the grading, and therefore the price, of a pink diamond.

There are 3 important factors in understanding the colour of pink diamonds;

HUE is the dominant colour of the diamond. Sometimes there are modifying colours or tints that affect the hue.

TONE is the amount of lightness or darkness in the diamond. The range extends from light to dark.

SATURATION is the strength or intensity of hue. The saturation of light in diamonds can vary from pastel to vivid and intense. The darker and more intense the colour, the more rare and more valuable the diamond.
