If the specification of obsidian is very small, its weight may also be very light, so it is impossible to distinguish the true from the false only by weight. The way to distinguish between true and false: stick obsidian placed at room temperature on people and feel its coolness. If it's extremely cold, it's true. In addition, if your obsidian is rainbow-eyed obsidian, you can know whether it is true or not even if you don't use the previous method to identify it. Therefore, the rainbow eye is only medium and high quality natural obsidian. Back to the so-called "augite" is actually acidic volcanic glass-that is, natural glass!
