The purity, rarity and exceptional brilliance of diamonds have made them the most precious stones in the world and the absolute symbol of eternal love. Their name comes from the Greek "adamas", meaning invincible, in reference to their extreme hardness.
Diamonds come in a variety of colours, ranging from the so-called "colourless" diamonds whose colour is classified according to an internationally recognized scale, to those rarer cases of diamonds with clearly-defined colours, such as yellow, blue, pink, champagne, black or green.
A diamond's quality depends on perfect combinations of four criteria, subject to endless variations that make each gem unique.
The black diamond is one of the most fascinating coloured diamonds. Unlike the colourless diamond or diamonds of other colours, the black diamond is opaque.
The physical particularities of the black diamond require a cut of exceptional precision, so as the better to bring out its uniformity of colour and exceptional brilliance.
Placing the black diamond alongside the white diamond emphasises the contrast and brings out the personality of this unique stone.
