The pink diamond is the “gorgeous gal” of the coloured diamond fraternity and a beautiful treasure that is a graceful symbol of femininity the world over. Pink diamonds are opulent style icons and they make no apology for their ostentatious presence. Much loved by Hollywood starlets, pink diamonds always make a grand entrance when they enter the room.

Diamonds of this colour are a rare treat and the purple hue is a result of the internal grain formation. How the stone is cut will have a major bearing on how much colour is discharged, and such is the scarcity of the purple diamond that the world still awaits a find of any historical significance.     

Diamonds of a genuine green hue are formed as a consequence of being exposed to radiation over many centuries and consequently they are a rare joy. Only one new green diamond type would be presented to the market annually, so these “jolly green” gems are held in very high esteem.

The true black diamond is hypnotically beautiful, absorbing almost all the light it encounters and coming in a range of dark hues from jet black to greys. The black diamond has always been a collector’s piece but now the “fashion” crowd is starting to acknowledge the unique qualities of the “night stone.” 

Champagne, Cognac and Brown diamonds together comprise the biggest selling coloured diamond category in the world with annual sales exceeding 5 billion dollars. With their tasteful colourings and “uptown” sophistication these gems are favoured by royalty, collectors and glitterati alike.

The olive diamond lies within a separate colour category to the green diamond and is usually imbued with elements of grey, black, brown and yellow. These elements impregnate the olive diamond to create a hue that is vastly different to the green variety.

The grey diamond is a rich fusion of black and white hues and the “steely” appearance can often lead the untrained eye to think it is a colourless diamond. These grey diamonds are greatly admired and the grey colour pigments that are prevalent in these stones serve as a salient colour modifier in many other coloured stones.

Like the red diamond, a pure orange diamond is so rare that few people within the jewellery industry have
ever encountered one. Conversely orange diamonds with a yellow or brown tint are more common but
they are hardly ubiquitous and are considered a cherished collectable
of immense value.
