Is obsidian a superstition that can ward off evil spirits?

Obsidian belongs to a kind of igneous rock. Many people think that obsidian does not belong to crystal, but the composition of obsidian is mainly SiO2. Since prehistoric times, it has been used to make tools, weapons, masks, mirrors and jewelry. This very sharp piece of natural glass is made into blades, arrows and daggers. Because obsidian itself is the most attractive gem among all spar, obsidian was used as an exorcism tool or even a treasure in ancient China and even in the west. In addition, because obsidian corresponds to the undersea wheel, it is quite useful for stability and peace, even for people who are sick or insomnia. Wearing obsidian helps to improve. Mexicans call this kind of stone "Tezcat". The mirror polished by obsidian is a tool used by wizards for divination.

Therefore, on the whole, obsidian with these characteristics is naturally puzzled.
