The popular image of the diamond is of a rare valuable stone with exceptional hardness and brilliance - and colorless that somehow symbolizes its pure nature. Most people think of diamonds as colorless almost by definition, so the concept of diamonds with color is, at first, a little baffling.

Yet diamonds not only occur in color, but are the only gemstones to occur naturally in all color families. Even white or near-colorless diamonds have color centers – meaning, all diamonds have the potential for color. Those that occur naturally in color are called natural color diamonds or natural fancy color diamonds.
