Hematite stones are known for protection and to deflect negative energy. The bracelets are custom made so most special requests within reason can be accommodated. You can choose between 8- or 10-mm sized beads depending how prominent you want your bracelet to be. This is an 8 inch bracelet, but if you need a size adjustment please contact me by chat, email at letiticia5126@yahoo.com, or fb at letiticia lynn poston for custom orders.
