Lava rocks/stones are basically made from the rocks that are left after a volcano erupts and then the mass that comes out cools and forms the rocks.
Lava rocks are very porous and absorb and diffuse essential oils. Add a drop of essential oil onto the lava rock, allow it to soak in, then wear and enjoy the fragrance.
You can use more than one essential oil on you lava stone, just wait a day or so between applications so that the scent of the previously applied oil has faded.
