Coleman Mine, near Jessieville, Garland County, Arkansas, USA
Large Cabinet, 48.0 x 30 x 15.0 cm

Look at the hand for scale... this is a HUGE PLATE that is in extremely good, in fact pristine, condition. I have seen many big quartz plates over the years but few of this size extracted with such care and luck as to have no damage. It is surely a museum piece and is very impressive in person. Get out a ruler to see how big this is! Largest crystals are to 15 cm.
