color change garnet

Among the garnets that are the birthstone for January, this term refers to garnets that exhibit a color-changing effect, where the color appears to change depending on the light source. It is sometimes called the "Alexandrite" because it changes its color from blue-green to green under natural light or fluorescent light, and turns red or purple under incandescent light, similar to alexandrite. Compared to alexandrite, I don't think it would be difficult to obtain one that is relatively large and has an easy-to-understand color change effect.
