Almost all crystals wear a left hand, except Obsidian, who wears a right hand. Obsidian absorbs energy. Wearing obsidian on your right hand helps to absorb their negative energy, including unclean things or diseases. Therefore, it is recommended that you wear obsidian bracelets on your right hand.
It can mainly absorb a lot of negative energy, but it will not be removed, so obsidian must be thoroughly purified within a certain period of time.
Of course, if possible, it is best to use crystal cave clusters for purification, and it is best to do purification work 2-3 times a month. Its absorbability is very strong, and if it is not purified in time, it may have a bad influence on the body. There is a moonlight bath. It is suggested that the full moon on 15 should be illuminated for one night, or it can be washed with running water 1 minute. The easiest way is to soak in pure water for one night.
