You are looking at a black obsidian skull. The skull is 5.3inches long, from front to back. Please notice there have a line shows on the surface of the raven skull. After finally perfecting a rough design, Skullis artists spent over two months working out the details for our new geometric crystal skull sculpture! Much careful dedication went into polishing each facet while avoiding causing damage to the adjacent facets! The result is a surreal black obsidian faceted crystal skull unlike any other! This single piece sculpture is carved from a solid black obsidian specimen from the United States.
