The phantom crystal is recognized by a "phantom" crystal within the crystal.  The phantom is comprised of a white or colored mineral and may be partial or complete.  The phantoms within a crystal provide an indication of the experiences, and the transformations, which the crystal has encountered during its evolution.  The phantom crystal has experienced numerous lifetimes, of learning and "being", while continuing in the same physical configuration; the crystal represents the many phases and the many types of life which may be experienced during ones lifetime. 

A phantom crystal symbolizes universal awareness.  Its purpose is to stimulate healing for the planet and to activate healing abilities in individuals.  For this purpose, it connects to a spiritual guide and enhances meditation.  A phantom quartz facilitates accessing the Akashic Record, reading past lives and recovering repressed memories to put the past into context.  It can also take you into the between-lives state.  In healing, a Phantom Quartz treats hearing disorders and opens clairaudience.
