Add a few drops of essential oil to the top surface of the rock for a natural diffusion effect. The complex rock structure allows the oil to spread and soak into the surface of the rock and diffuse evenly over time.
Each lava rock is hand-picked from a lava field in Arizona. They capture a unique moment in time. Lava rocks form as magma rapidly cools and forces internal gasses to quickly escape - creating a natural diffusion surface.
