Lavastone is naturally porous, so you can add a drop of your favourite essential oil to the lavastone bead and the scent will diffuse gently over approx a day, depending on the oil (I have found that very good quality oils can last for quite a while). Once the scent has faded, you can replace with the same or a different oil.
