Lava stone is porous, making it a great natural essential oil diffuser! Apply a few drops to large lava stones, or apply one drop to two or three of the smaller lava stones. Let your oil soak in before wearing, or rub it in with a q-tip. I like to pick my scent out the night before,
and leave a few drops on the necklace to soak in overnight and diffuse while I sleep. The scent will wear off naturally in about a day, depending on the essential oil chosen.
