Alexandrite is a rare and remarkable gemstone prized for its unique ability to change color in different lighting. Often called an “emerald by day, ruby by night,” this captivating gemstone shifts from a beautiful blue-green in daylight to a deep red-violet in incandescent light. Originally discovered in Russia's Ural Mountains and named for Tsar Alexander II, alexandrite is said to bring good health and fortune. The more distinct its color shift, the more valuable the gemstone.

This phenomenon occurs because of the way alexandrite absorbs and reflects light. In natural daylight, it appears as a cool-toned blue or green. Under artificial light, such as a lamp, it transforms into a warm-toned deep red or violet. This unique quality makes alexandrite jewelry a fascinating conversation starter.
