The intriguing alexandrite stone is valued for its exceptional capacity to change color. Frequently referred to as “emerald by day, ruby by night,” this fascinating gemstone exhibits a captivating color change that varies based on the illumination. Alexandrite stone is generally bright green or bluish-green in daytime, but it can turn reddish-purple or even blazing red in incandescent light. Pleochroism, a distinctive feature of alexandrite, is what makes it so desirable to jewelry connoisseurs.
