Beautiful raw, water clear Herkimer Diamond.  With the naked eye, all seen internally is a speck of black hydrocarbon. Anthraxolite is the traditional name of the black material commonly found in Herkimer Diamond mines. It was thought to be a relative of anthracite (coal), decayed plant material that fossilized. However, new evidence suggests it is a black hydrocarbon, a thick oily substance. The new theory suggests that hydrocarbons moved through the cracks and vugs along with dissolved quartz, salt and other minerals in the earth. At some point these fluids solidified. It is found inside Herkimer's as well as surrounding them, suggesting it was present before, during and after the crystals formation.  It gives this Herkimer crystal a deep rich hue.
Externally, specks of black hydrocarbon are found near one tip.  An oddly shaped key lies near the other point, noticeable in the pictures.
An activation facet is also found on this raw Herkimer Diamond with incredible clarity.
