Alexandrite is the color-change variety of the gem species chrysoberyl, which is well-known for its chatoyancy, also known as its ‘cat’s eye effect’. Often referred to as an ‘emerald by day and a ruby by night’, alexandrite displays one of the most extraordinary color changing qualities of all gemstones, turning green in sunlight and red in incandescent light. Along with the diamond, emerald, and ruby, high-quality alexandrite is one of the most expensive gemstones in the world. Alexandrite is one of three June birthstones.
