An essential oil diffuser is an absolutely essential item for your home and creates the perfect mood when you add your favourite oils.  We love this stone ultrasonic diffuser as it has 3 light settings in the ring at the base so it doubles up as a beautiful piece of home decor.  Simply add 10–15 drops of your favourite essential oils, fill with water and then choose your light setting.  You don't need to worry about switching it off, once the water tank has emptied it will automatically turn off.
