Clusters radiate very strong potent energy in many directions. These are wonderful for gridding your home or room. You can also place other stones on quartz clusters to amplify the properties of that stone. For example, need the properties of Ruby, but can only afford a small piece? Place that small piece on a quartz cluster, and you’ll have the energy of a Ruby almost equal to the size of the cluster it is placed on. Clusters do not cleanse things, this is common misinformation.
