This type of amethyst posseses energies which allow it to be represented as one of the finest third eye stones, stimulating visions into unknown realms both within the self and into exterior worlds. 
A great stone for auric cleansing, it helps with the perception and interpretation of the auric field. It emmanates a concentrated energy that is forceful, yet subtle, that aids in dissipation of lower vibrations from the aura.  This mineral stimulates the "bighter" aspect of the individual as it encourages warmth and the purity of love within ones being. 
This stone is great for journeying and self-evaluation. It also allows one to re-trace any negative energies which attempt to penetrate ones protective shield, providing information with respect to the reasons for, and the origin of, the negativity.
