Barite on Calcite, attr: Minerva #1 Mine, Minerva Oil Company, Cave-in-Rock District, Southern Illinois, Mined c. late 1960s, Bynum Collection, Small Cabinet 3.5 x 4.0 x 6.0 cm, $100. SOLD
Combination of light pastel blue bladed barite and light brown elongated calcite scalenohedrons. Displays equally well from either side and in great condition. Upon more examination, I would attribute this to the Crystal/Victory Complex in Spar Mountain. Minerva Oil Company is still the likely operator as they acquired the mines prior to the time the piece was collected. Bynum Collection.
