Baryte      Montreal Mine, Montreal, Wisconsin.  Ex. Harold L. Dibble collection.  I don't see many of these around and have only owned a few, of which this one is the finest by a large margin.  It has big, milky/transparent, well-terminated crystals with glassy luster on one side and satin luster on the other.  All the large important crystals are damage-free while a few small ones near the bottom edge show damage.  This could be trimmed if the damage is concerning and the size of the piece would not be dramatically reduced.  Now it measures 8.1 x 7.1 x 6.6 cm overall.  The largest crystal is 6 cm.  I've never seen crystals from this location even half this size before.  $475
