Extraordinary museum quality plate of glass clear qyartz crystals from the Arrowhead Mine in Mt. Ida, Montgomery County, Arkansas. Perfect condition, zero damage. Photos do not begin to do justice to this awesome piece. Measures 21 x 15 x 5 inches (50.8 x 38.1 x 12.7 cm). Must be seen to be fully appreciated and would probably need to picked up at my shop, too big to ship. Dug around 2008 by Matt Price.
