The Science Behind the Alexandrite Effect 

Every natural phenomenon carries a science behind it. For Alexandrite, the color changing property is due to the presence of elements like chromium. The presence of these trace element gives the characteristic color to the stone that changes under different light conditions. The gemstone shows a purple-grey color in uniform white light. The blue-green hue of the stone is due to the unabsorbed green and blue light. (Unabsorbed light reflected gives objects the same color) The 'warm light' as we consider incandescent or candlelight, the stone appears purple-red. This peculiar color is due to the chromium ions not absorbing much red light.
