Ex. Chicago Field Museum from Wards Scientific, circa 1895

A very large Calcite specimen from a classic location mined in the late 1800s. It is highly likely this is the largest specimen currently available from the location. There is a thin layer or reddish brown colored Hematite just below the surface of the Calcite crystals which is only present on one side of the crystals. On the opposing side of the crystals, the Calcite is white to clear in color. The luster on the sides of the crystals with the Hematite is highly glossy whereas the luster on the clear to white sides of the crystals is glassy.

Condition:

Flaws: There are quite few places where the Calcite is cleaved and bruised.
