Agate is a stone of strength. ... 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.
It cleanses and stabilizes the aura, eliminating and transforming negativity. Agate enhances mental function, improving concentration, perception and analytical abilities. It soothes and calms, healing inner anger or tension and creates a sense of security and safety.
