Agate enhances creativity and strengthens the intellect. 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.
Agate is a very protective stone. It is especially protective for children. Agate is also used to protect against harmful spirits.
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. 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. It can help one to accept one’s emotions, thereby helping overcome those emotions that one wants to remove.
Because of the harmonizing qualities of agate, and its emotional energies of removing and releasing resentments and bitterness, it is also considered by many to be an excellent stone for helping to heal and improve relationships. Agate can cleanse and stabilize the aura by removing and/or transforming negative energy.
