Agate is a stone of strength. It was used by the Ancients on the breastplates of armor to give warriors strength and make them victorious in battle. Energetically, it is considered to give strength in both battle and physically.
Agate enhances creativity and strengthens the intellect, making it a beneficial stone for both students and artists. It is also known as a good luck stone. As a stone of harmony, one of the things agate does is balance yin/yang energy. Agate increases energy.
