This is a Royal Purple Aura double terminated quartz crystal. You will receive DT Crystal A that is featured in the photos. Please be aware - DT Crystal A is chipped on one side - it came that way. This crystal or any crystal with the name "Aura" has undergone a treatment where atoms and molecules of metal vapor are bonded to the surface of the crystal, creating an intense iridescent coating. The metal vapors used for this treatment is usually Titanium, Niobium, Cobalt or a combination. Double terminated (DT) have points at both ends of the crystal. A DT radiates or absorbs energy at both ends simultaneously, channeling it in two directions at once. A stone of balance, a DT integrates spirit and matter and can provide a bridge between two energy points. Royal Purple Aura embodies the purple ray; it is the color of intuition, imagination, psychic/metaphysical abilities. This crystal can assist you in increasing your spiritual gifts.
