Color Change and UV Reactive Garnet from the Umba Valley, Tanzania. Shifts from light tones in daylight to a richer orange-red under incandescent light, and fluoresces a vivid red under UV. Garnets from the Umba region are well known for unusual trace element chemistry, giving rise to optical effects not commonly seen in garnet. The combination of color change and strong fluorescence makes this material especially desirable for collectors and cutters seeking rare phenomena
