With the natural heft of solid marble, the organic material and smooth form of the Expanse Oil Burner makes for a striking addition to your ritual practice. The distinctive grain of marble is unique to each Oil Burner, adding a unique and compelling feel to your space even before the candle is lit. Once lit, the warming of the stone adds an earthy feel, as it diffuses your chosen essential oil through the room, transforming it to one that suits your mood.
