Alexandrite is a rare and precious gem which changes color when viewed in natural and artificial light. It appears green in the daylight and red in incandescent light. Variations of the gem can appear anywhere from yellow to pink during the day and a richer red during the night. These color changes result from a change that occurs rarely within alexandrite's larger mineral group, chrysoberyl, in which aluminum is replaced by chromium ions in alexandrite's structure; this replacement absorbs light wavelengths within the yellow spectrum, making the gem appear to change color in different light sources.
