Agate crystals vibrate on a lower, more gentle frequency. There are many types of agate that provide different healing properties depending on their variety. In general though, agate healing properties are slow and steady. They aren’t as intense as crystals like clear quartz or selenite, but they radiate a soft strength to ground the spirit with a sense of stability. Agate properties connect with the energy of the Earth. They are thought to bring harmony to all aspects of the being, physical, spiritual and emotional. Using agate during times of unbalance, when it feels as if the yin and yang within you are operating out of proportion, can reintroduce an equilibrium to your tempered soul.
