Linked to the powers of elemental Air and renowned for centuries as the 'stone of peace', Blue Lace Agate is believed to reduce tension, encourage calmness and heal the effects of stress. It is said to be especially soothing for sensitive people who are at risk of being overwhelmed by their own or other people's problems and for violent people who find it difficult to control their temper or talk about their anger. Blue Lace Agate is said to help you connect with your suppressed feminine qualities (whether you are female or male) so that you can become more empathic and sympathetic to others.

Blue Lace Agate is believed to increase the magical power of the voice, granting the wearer a silver tongue and the ability to speak from the heart. It helps you to express your feelings eloquently and talk to other people about difficult issues without causing guilt, anger or resentment.

Blue Lace Agate is used in crystal healing to deal with the effects of stress and tension, and is thought to be especially good for headaches. Place a piece of polished stone on the forehead or 3rd Eye and visualize the pain being drawn into the Blue Lace Agate. Once your headache has eased you should clean the stone under running water and leave it to dry naturally. A piece of Blue Lace Agate under your pillow brings a deep and healing sleep, and it is supposed to be a very good stone for soothing restless babies and young children (though obviously a young child should never be left alone with any stone or crystal because of the risk of choking).
