Alexandrite is an incredible gem, it can be shown in a variety of colors (alexandrite effect) depending on the nature of the ambient light. The alexandrite effect is the phenomenon observed in the color change from green to red with the change in the light source. To make it clear: the color variation is independent of the viewing angle; a gem that changes color with the angle of view is known as pleochroic, and while alexandrite has a strong pleochroism, it also changes color regardless of the angle of view, depending only on the light source. Its price per carat can reach 100,000 dollars.
