Obsidian is a rock which is a type of naturally occurring glass produced by volcanoes. It lacks crystal structure, which can make it have extremely thin edges. This is the reason why obsidian was often used as arrowheads in a variety of ancient cultures. You can have your very own arrowhead to show to your friends! A great collectible item for the Native American art collector!
