Alexandrite's main characteristic is the ability to change color if exposed to a light source that is rich in red rays. This metamorphosis is called Pleochroism. Under such light, such as candlelight, or artificial light, the stone turns red or reddish. This pronounced color change is highly prized. The most valuable alexandrites are brilliant green, and change color to a fiery red under light. The most drastic color changes are the most desirable, as if you were watching a traffic light change color. Usually there is a color bleed through from one color to the other, or there is too much impurity to start with to permit such a drastic color change.
