The Stone Diffuser

Designed and made by Maddalena Selvini for Basium in honour of nature and its natural forces.

Crafted from stone dust, this unique diffuser is the product of a transformation process of sand becoming rock in nature. As stone debris is collected and exposed to high temperatures, it solidifies into Arena — a material with an earthy, weathered texture and rich porosity, ideal for releasing fragrance. Inspired by the raw, automatic creation of sand through rivers and tides, each diffuser embodies a quiet strength and inevitability, much like its origin.
