Alexandrite

Colorful| Wisdom | Integrity

Alexandrite is a rare mystical gem that is the color-change variety of chrysoberyl, an aluminate of the mineral beryllium. It is most famous for its dramatic color-change from emerald green in daylight to violet reds in incandescent light. 

This characteristic change is known as the "Alexandrite Effect" and is due to the gemstone absorbing equal amounts of green and red from a spectrum of white light. The stronger the change, the more valuable the gem. 

Pleochroism is also present in Alexandrite, not to be confused with its famous color-change. Pleochroism is the change of body color when tilting or rotating in a consistent light source.
