Obsidian or black crystal, which absorbs negative energy better?

Obsidian is famous for its professional evil spirits. Its function is to ward off evil spirits, that is, to keep evil spirits out of the body.

Black crystal, in the crystal industry, there are two views. One is to call Mo Jing (also known as Tea Mo Jing) a black crystal. Then, this kind of black crystal belongs to tea crystal, but it has no function of avoiding evil spirits. Another way of saying this is to call the dark-haired crystal "black crystal". Then, black hair, with powerful energy, can exorcise evil spirits, resist foreign evil spirits, and dispel existing evil spirits in one's body. Except these two kinds, there is no black crystal in nature.

Therefore, if you can confirm that your black crystal is black hair, the effect is that black hair is stronger. If you are not sure what kind of black crystal you are. Or wear obsidian honestly. After all, it is a "professional exorcism."
