This is an exceptional Pyrite cluster with many beautiful Pyrite formations. There is a beautiful and thick layer of Calcite coating throughout this cluster. Some of the Calcite has clustered and formed naturally terminated points. Very nice! There are even a few patches of Red Calcite! A flat wooden stand, measuring 6.5 x 5.5 x 0.75 inches (16.5 x 14 x 1.9 cm) is included with this cluster.
