This specimen consists of a cavity in a semi-crystalline matrix of magnetite. Large octahedral magnetite crystals grew in this cavity, which was then filled with white massive calcite. The exposed magnetite crystals range in size up to 0.8" (2.0cm) on edge. There is some damage to this specimen, primarily along the edges, where it was broken away from the host rock.
