Fluorite    Chashan Mine, near Chenzhou, Hunan Prov., China.  When first introduced these fluorites were insanely popular.  Very expensive and almost always in huge cubes and big groupings far too big for the average collector.  Most also badly damaged.  This is one of only two I could find in cabinet sized pieces (strange to have to look for SMALL specimens).  8 x 6 x 4 cm with cubes to 3.5 cm on edge.  Gem clear crystals with a nice light green cast.  Cubes have minor dodec. modifications.  One small cube near edge has a dinged corner.  A nice value at only   155$
