Watch this incredible moment the dazzling interior of an obsidian rock is revealed after it is cracked open. <br /><br />The filmer holds a filthy rock in their hand and taps the side of it with another rock following up with a much harder smack. <br /><br />A visible crack occurs down the side of the rock when the filmer takes hold of both halves. <br /><br />The rock is then slowly opened out to reveal the bright night-black obsidian inside. The difference of this rock's stunning interior compared to its dusty exterior is so stark it shocks the viewer.
