a polished agate

Complex bands of white and black cover the oval surface of this expertly polished agate. The agate looks like an evil eye staring out. The iris is made up of a brown band surrounded by a white band. A compressed black band at the center acts like a pupil; opening up like a pit, a window into nothing.
