Fluorite, Rosiclare Level, Minerva #1 Mine, Ozark-Mahoning Company, Cave-in-Rock District, Southern Illinois Medium cabinet 5 x 8 x 8 cm $350. Online 3/19 SOLD
Glassy group of brown/yellow fluorite from advance mining c. 1990-1992. Note the spherical indentation towards the center of the specimen: barite precipitated here and was subsequently dissolved naturally in the pocket. Also, note 'V' shaped inclusions within the crystals and a thin but distinct purple rim as typical of this orebody. A classic specimen from the mine in great condition.
