This is a beautiful Tiger Eye Skull. It has many areas that are highly Chatoyant which I wasn't able to catch in the pictures. It measures 1.59" from the front of the jaw to the back of the skull.
Metaphysically Tiger's Eye (Tiger Eye) is a stone of protection that is also very grounding. It enhances integrity, willpower, practicality and correct use of power. It is a stone that enhances good luck, and brings prosperity, often in the form of money. Tiger's eye is also a very protective stone which is especially protective during travel. It can also help one see clearly without illusion. Tiger's eye brings a special boost to the solar plexus chakra and to one's personal power.
