Color-change gemstones display differing hues under indoor incandescent lighting and outdoor sunlight, with alexandrite chrysoberyl being by far the best known of these. However, the phenomenon can also be encountered in sapphire, garnet, spinel, fluorite and diaspore, with the latter often sold under the trade name “zultanite”.

Although artificial incandescent light and natural sunlight both contain the full spectrum of colors, the relative intensity of each hue varies between these two so-called “white light” sources. For example, the somewhat yellowish incandescent light bulbs tend to emit larger quantities of low-frequency red light, so color-change stones tend to be somewhat reddish when worn indoors. Conversely, mid-range wavelengths are predominant within sunlight, and the same stone will therefore appear more greenish after moving outside.

It should be noted that specimens that undergo a very minor change within a single hue (e.g. red to pinkish-red) are instead known as color-shift gemstones.
