Agate is a rock consisting primarily of cryptocrystalline silica, chiefly chalcedony, alternating with microgranular quartz. It is characterized by its fineness of grain and variety of color. Although agates may be found in various kinds of host rock, they are classically associated with volcanic rocks and can be common in certain metamorphic rocks.
Agate crystals vibrate on a lower, more gentle frequency and provide different healing properties depending on their variety. In general, agate healing properties are slow and steady as they radiate a soft strength to bring 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.
