This essential oil diffuser necklace is made with a natural porous clay disk mounted in a silver plated pendant. Just place a drop or two of your favorite oil on the clay disk. Once the oil has been absorbed you are ready to enjoy the therapeutic benefits of essential oils! Once the diffuser no longer gives off the desired scent, refresh the scent by adding another drop of oil to the surface of the clay.  Pendant measures approximately 1" in diameter and comes with a 24" silver plated chain.
