NOVELTY - The utility model claims a healthcare crystal stone chain for releasing far infrared negative ion, comprising a permanent magnetic ball core; the outer surface is a terahertz stone layer, an electric stone layer, graphene layer, each layer is formed by adhesive; the permanent magnetic ball core outer side is connected with terahertz stone by adhesive; the outer side of the terahertz stone is connected with tourmaline through adhesive; the tourmaline is connected with graphene through adhesive; the graphene outer side is provided with a biological nanometre coating, The healthcare barite chain of the utility model can be mutually attracted and connected through the permanent magnetic ball core; it also can be drilled on the N pole S pole of the permanent magnet ball; the elastic rope is used for connecting and forming. The healthcare barite chain can improve respiratory system, enhance human immunity, separate red blood cell, improve blood circulation, enhance brain blood supply and oxygen supply, improve sleep, eliminate anxiety, increase cell activity, activate immune cell function, promote cell metabolism.
