These minimalist simple essential oil diffuser earrings are made with natural lava bead and gold plated brass ear hooks. Apply 1-2 drops of therapeutic grade essential oil to the lava stone, then allow a moment for oil to absorb and wipe off the excess. Because lava beads are porous, they will hold the essential oil for 1-2 days. !!! It is important to note that you should only use essential oil that is safe to come in direct contact with the skin, as you will receive topical as well as the aromatic benefits. Please note: ESSENTIAL OIL IS NOT INCLUDED! Specifications: Gold plated brass Length: varied
