Conceived by Brooklyn, New York-based design studio, Walden, this handpicked lava rock suspended on an anodised aluminium base is designed to diffuse essential oil. A juxtaposition of materials that beautifully contrasts the sleek precision of the simple base with the rawness of the lava rock.

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.
