Stone Color
Diamonds range from colourless, being the rarest and most valuable, to yellowish with a spectrum of shades in between. As these yellowish tones become more apparent, the rarity and cost of the diamond decrease.
However, when a diamond's colour is more intense than the "Z" grading, it enters the realm of "Fancy Colour". In this case, the intensity of the colour in the diamond plays a major role in its value. The value of a Fancy Colour Diamond may far surpass that of colourless diamonds if the intensity of the colour is high and the colour is rare. A diamond may come in all colours of the rainbow.
While the prices are higher for colourless diamonds, the most valued colour is a matter of personal preference. Some prefer the very transparent D-F range, while others may opt for the "warmer" colors in the G-J range or diamonds with a clearly visible tint.
The charts below represent these colour variations and their respective GIA grades and traditional terms.
