This awesome skull was carved from an agate geode lined with amethyst crystals. It comes from Brazil, measures 7.6 inches long (from front to back), and weighs 8.3 pounds. Its presence may attract adventuresome fedora-wearing, bullwhip-carrying professors of archaeology to your door. So, if you decide to put it on your mantle, please do the honourable thing and make sure your home is free of snakes.
