The term "Fancy Sapphire" refers to Sapphire stones that are not the traditional blue- they can be pink, purple, orange, yellow, green, black... even colorless. The pinkish-red Sapphire called Padparascha is considered a Fancy Sapphire. There is also a Fancy Sapphire whose shade changes hue under different light sources. These color variations are due to chemical impurities in the stone such as traces of iron or chromium. Sapphire is one of the most varied stones in terms of hue, and depending on the shade, Fancy Sapphire varieties come in various intensities, saturations, and values.
