Color-change sapphire, a captivating variety of Corundum, exhibits a remarkable shift in hue depending on the light source. Typically, these Sapphires display a blue to violet color in daylight or fluorescent light, and transition to a purplish-pink to reddish-purple tone under incandescent light. This fascinating optical phenomenon is often attributed to the presence of trace elements like vanadium and chromium. With a hardness of 9 on the Mohs scale, Sapphires are exceptionally durable. The color-change variety, prized for its rarity and unique visual effect, is a highly sought-after gemstone among collectors and jewelry enthusiasts.
