Most diamonds appear icy white, but many have tiny hints of colour. Diamonds
are graded on a colour scale established by the Gemological Institute of
America (GIA), ranging from D (colourless) to Z.
Colourless diamonds are extremely rare, and therefore very valuable. But there are no hard and fast rules for what colour makes a diamond beautiful. The Incomparable, one of the world's most beautiful diamonds, contains hints of brown, smokey amber and champagne colours.
The Incomparable was discovered in the Mbuji Mayi district of the Democratic Republic of Congo (formerly known as Zaire), almost a decade before the Millennium Star was discovered in the same region. Please note: colour calibration of monitors can vary considerably and the colour spectrum shown is meant only as an educational guide. |

Weighing a massive 407.48 carats, the Incomparable is the third largest diamond
ever cut, surpassed only by the Cullinan I and the Golden Jubilee. The stone is
remarkable for its unusual triangular shape, called a "triolette", and its
fancy brownish-yellow colour.
