If you want to make a fortune, you have to face outward. You'd better choose your left hand when wearing it, because the left hand is interpreted as a holy hand in Buddhism and should be clean relative to the right hand, so a clean hand will not destroy the aura of the brave. Therefore, if you wear obsidian facing outward, it can play a role in ward off evil spirits. Obsidian can stop evil. Wearing it on your body will definitely get rid of bad luck.
