Dark gray, almost black, colored Hetaerolite crystals have covered the surfaces of stalactic Hematite. Calcite crystals have grown on the surfaces of the Hetaerolite. These crystals have sharply pointed terminations and range in color from clear to honey yellow to reddish. The reddish colored crystals are included with Hematite and are found at the bottom of the specimen and are larger than the yellow colored crystals on the rest of the specimen which are quite small.
Flaws: There are a few areas where the coating of Hetaerolite is not present and the underlying, reddish colored, stalactic material is showing.
