Color

In diamonds, rarity equals value. With diamonds in the normal range, value is based on the absence of color, because colorless diamonds are the rarest. With fancy color diamonds-the ones outside the normal color range-the rarest and most valuable colors are saturated pinks, blues, and greens. In all cases, even very slight color differences can have a big impact on value.

Red, green and blue diamonds with metium to dark tones and moderate saturations are extremely rare.
