Alexandrite
Alexandrite
Alexandrite is a rare and remarkable gemstone renowned for its extraordinary color-changing property. These precious stones are often described as “emerald by day, ruby by night.” This captivating phenomenon is due to the gemstone’s unique ability to appear bluish-green in daylight or fluorescent light and purplish-red under incandescent light, a result of the presence of chromium ions in its crystal structure.

Color and Value of Alexandrite
The most prized alexandrites exhibit a vivid and distinct color change from green in daylight to red in incandescent light. The intensity and clarity of this color shift significantly influence the gemstone’s value. High-quality specimens with strong color change and minimal inclusions are exceedingly rare and command premium prices in the market.
Common Cuts and Applications
Gem cutters typically cut alexandrite into shapes that enhance its optical characteristics, such as oval, cushion, and round cuts, to maximize the visual impact of its color-changing property. It is a popular choice for rings, pendants, and earrings. The unique and dynamic appearance of Alexandrite that changes with lighting conditions makes it suitable for a variety of applications.
