This one is great on its own or in a stack with others. The hematite is said to be both calming and protective with a grounding energy. It helps deflect negativity and aids in reducing stress and worry. This bracelet is strung on elastic cord and is just under 7 inches so it fits gently at wrist, not hanging on hand. For longer wear and tear, gently roll the bracelet over the wrist, do not stretch over the hand as this puts pressure on the cord.
