This is a WHOPPER fluorite from Ruyuan, China. These are not coming out any longer; they were available in decent supply for only a very short time, and then became expensive shorty thereafter, and they still are. This huge crystal is complete all around, and is sitting nicely on a carefully-trimmed matrix. The internal fracturing you see is normal for these. 12.4 x 10.3 x 6.3 cm
