Pleochroism - Pleochroism is an optical phenomenon where due to double refraction of light by a colored gem or crystal, the light is divided into two paths which are polarized at a 90° angle to each other. As the divided light follows different paths within the stone and are traveling at different speeds, they may have the result of differential selective absorption, thus when they leave the crystal they have different colors, making the stone seem to be of different colors.
