A group of witherite crystals 2.5 by 4.0 cm perched on barite with micro-alstonite, traces of purple fluorite and cinnamon-brown sphalerite. Classic bipyramidal doubly terminated witherite from the premier location for the species in Southern Illinois. In great condition. A little local flavor about this piece - Ben Clement hired a contractor to do work for him and paid the man in minerals and cash. Ron Roberts acquired this piece many years later from the contractor.
