Minerva # 1 Mine, Cave-in-Rock, Hardin County, Illinois

BaCaCo₃

This specimen is composed of hopper growth, heaxagonal crystals. This crystal habit is seldom seen in Witherite and as far as I know only found at the Minerva Mine. The crystals are quite large for the species; the most predominate crystal is 3.3 x 1.8 x 1.7 cm. There are a couple of crude Sphalerite crystals at the base and some small purple Fluorite crystals. The specimen is in very good condition.

9.5 x 9 x 7.7 cm
