This beautiful necklace is handmade with all natural hazelwood and fresh water pearls. The way it works is the hazelwood actually absorbs the extra acid and while it does, the wood gradually turns a darker brown color. In order for the body to be at it’s best healing level, it should be slightly more alkaline. When your body is higher in acidic pH, you are susceptible to more illnesses and pains. By helping it be more alkaline, it is better able to filter out toxins and help the body combat whatever may come its way.... CanyonLeaf Baltic Sea Amber + Gemstone Jewelry is made for wearing, not for chewing.  Our jewelry is not designed to be an amber teether or teething necklace and it should never be placed in the mouth.  Naturally.
