The energy traits classically associated with quartz are energy amplification, memory, light bearing and programmability. Quartz brings in so much light it is said to connect us with the stars. It can be used to beam light clear energy, heal wounds and connect us to our higher self. Quartz can also be programmed to hold an intent, which is useful in just about any situation from healing to manifesting; retaining that program until it is cleared. Quartz amplifies energy, whether sending or receiving, and it can be used to amplify the energies of other stones. Different formations and terminations have different characteristics; one can streamline intent by obtaining the correct formation. Clear quartz can be used for any spiritual pursuit including enhancing psychic abilities, communicating with spirit guides or other beings, channeling, dissolving karma, manifestation, healing, recalling past lives, astral travel and expansion of consciousness just to name a few.
