You are looking at a Smoky Quartz Rock Crystal skull. The skull is 5.6 inches long from front to back. Smokey quartz is particularly good for dealing with negative energies, both protecting from and dispelling energies already present. Smokey quartz is one of the most efficient grounding and anchoring stones and at the same time raises vibrations during meditation. This protective stone has a strong link with the Earth and the base chakras, promoting a concern for the environment and ecological solutions. This stone is a superb antidote to stress. It assists in tolerating difficult times with equanimity, fortifying resolve.
