Collection: ALEXANDRITE CAT'S EYE

Alexandrite cat's eye is a rare gemstone that combines two captivating optical phenomena: color change and chatoyancy (the cat's eye effect). It's a chrysoberyl variety known for shifting from green or bluish green in daylight to red or purplish red under incandescent light. The cat's eye effect, also called chatoyancy, is seen as a narrow, bright line that appears to move across the surface when the gem is rotated, due to parallel inclusions reflecting light.
