A crystal is a solid in which the constituent atoms, molecules, or ions are packed in a regularly ordered, repeating pattern extending in all three spatial dimensions.

The word crystal originates from the Greek word krystallos meaning clear ice, as it was thought to be an especially solid form of water. The word once referred particularly to quartz, or "rock crystal".

The Phantom crystal is comprised of a white or colored material and may be partial or complete.  The phantoms within a crystal provide an indication of the experiences and the transformations the crystal has undergone in its evolution.   

It is an excellent tool for meditation and for assisting one in connecting with the higher realms of knowledge.  It can also be used to access the records of ones progression through past lives.
