This is an incredible carved aqua blue obsidian dragon skull from Leandro de Souza that we nabbed in Tucson this year. There is a lot of argument over whether pieces sold on the market as colored obsidian are natural or manmade. We'll assume this is manmade glass, but striking nonetheless.
It is 5" long by 3.5" wide and 770g. It's absolutely stunning.
