This is an EMF protection necklace made with shungite and hematite. 【Shungite】 Contains a high amount of carbon and absorbs and neutralizes electromagnetic waves. It forms a protective shield that blocks radiation, while simultaneously detoxifying the body's electromagnetic field, reducing fatigue and stress. 【Hematite】 Contains a high amount of iron and absorbs and transforms negative energy, forming a stable energy barrier against electromagnetic waves. It also grounds the body, enhances concentration, and strengthens resistance to overstimulation from electromagnetic waves. Chain Length: Approximately 43cm Chain Material: Stainless Steel
