White Stone Oil Diffuser This white stone oil diffuser is a sophisticated way to bring refreshing, revitalizing and relaxing scents into your room, creating whatever atmosphere you desire for working, entertaining, or chilling out. The internal part of the diffuser is made from BPA-free plastic, which is protected by a porcelain cover, making it a subtle feature for any room. The white diffuser will fit in with most colour schemes and will simply blend in as another piece of decoration, so you can have it on display in pride of place on a shelf or mantlepiece or keep it out of the way on top of a cupboard. With additional features such as an LED light which adds a candle-like glow to the diffuser, this piece can enhance the ambience and atmosphere in any room on a number of levels.
