Gorgeous oval-faceted natural Sapphire gemstone, approximately .40 Carats and 5.05 x 3.97 x 2.09 mm. Mined in Tanzania, this stunning purplish-brown Sapphire displays a light color change, and although it shows no clear signs of being heated, we assume it has been. New, ships in a gem jar.

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.
