You are looking at a Blue Chalcedony Skull, with a very unique carving. The teeth and jaws are very nice. However, on one side the jaw is has some damage. That does not spoil the fun with this little fellow. Naughty, but also very funny, powerful. Personally it feels like he is able to create a blue field around your body, or fill the aura with blue light. He is sweet as well, and cuddly.
