Color change sapphire is a fascinating variety of corundum that exhibits a noticeable shift in color under different lighting conditions. The most classic example changes from blue in daylight or fluorescent light to violet or purplish-red under incandescent light, but other combinations exist, such as green to reddish-brown or yellow to peach-pink. This natural optical phenomenon is caused by trace elements like chromium and vanadium in the crystal, which absorb and reflect light differently depending on the light source.
