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. However, because it is a grounding stone, it does not increase energy at all times, but rather enables bursts of energy as needed. In this way, agate is a conservation stone, ¬†and enhances longevity.
Emotionally, agate gives courage, emotional strength, self-confidence, and dispels fears. It can also lessen feelings of envy by grounding the emotions. In the same way, it assists with acceptance of all things. It can be very beneficial for self-examination as well as examination of the circumstances one finds oneself in. These qualities make agate superior for easing anxiety and stress.
