The Purpose Diffuser Bracelet includes both Lava Stone beads and Pyrite beads. Pyrite is a protective stone that carries a masculine, assertive energy, which makes it ideal for encouraging action, persistence, confidence, and discipline. Lava beads are made of rocks that form when volcanoes erupt magma (lava) onto the surface of the earth and the magma cools. Lava beads are porous and can absorb the oil of your choice.
