An interesting rock from the Xianghualing Mine, Chenzhou, Hunan, China. The calcite is a deeper red than most I've seen from China. The rock also has a little scheelite that glows a bright whitish blue. The interesting unknown mineral that fluoresces grey. A well educated guess (not by me) is that it may be a rare mineral, Hsianghualite, found only at Xianghualing and its sister mine, Xianghuapu. But until testing is done on it or similar material, we'll not know for certain. Images are SW, MW and natural.
