You can wear as many crystal bracelets as you like for self discovery. However, when stacking bracelets, it is recommended not to wear more than three or four together. The number of crystal bracelets you can wear at once depends on your personal energy and sensitivity to the stones.  Some people find that wearing too many different crystals at once can create overwhelming energy, while others feel balanced. It's important to listen to your body and adjust the number of bracelets accordingly.
