This specimen is from an open quarry, along the Mississippi River, which is right next door to the much better known Linwood Mine which in recent years has produced a flood of Calcite, Pyrite, Marcasite and particularly Barite specimens, some of which are quite spectacular. Despite the close proximity of the two locations, specimens are considerably different. The Barite of the specimen is clear in the interior but has a light peachy/pink outer layer. In places where the clear interior of the Barite is visible, small Marcasite can be seen to have been included. The surface of the side of the specimen with the Barite crystals, is covered with small, curved Dolomite crystals The opposite side of the specimen has more small Dolomite crystals as well as areas which are covered with a druze of small, iridescent Pyrite crystals.
Flaws: Only a partial crystal with two complete faces and part of another.
