Magnesite can trigger the brain with its soothing and calming properties, as well as aiding in creativity, clarity, and imagination. The grey lava stones are used to diffuse essential oils. They are raw lava beads with no enamel so they soak the oil in well, but you will replace with another drop of oil after 3-4 days. Lava beads have character and no two are the same. The gold TFWH charm is to remind the wearer of her strength and fire. These bracelets were created to help women trigger their sense throughout their day to create calm, and remember their strength. To best care for your diffuser bracelet, do not submerge in water for long periods of time, or expose to harsh chemicals to keep gold from tarnishing.
