Cluster Quartz
Quartz clusters radiate energy out to the surrounding environment and can also absorb negative energy. These crystals have all the properties of quartz. They can be programmed and left in place to do their work. They are especially useful for cleansing a room or other crystals, in which case the crystal should be left overnight on the cluster. Cluster crystals are used for meditation and healing purposes. They can expand the mind to reach the spirit world.
