Aura Quartz is a natural quartz crystal with manmade modifications to create its signature iridescent appearance. This “aura coating” is created by fusing precious metal particles like titanium or platinum to the surface of the crystal in a high-heat vacuum chamber. 
Aura quartz is often considered to have many of the same metaphysical or spiritual healing benefits as quartz itself. Quartz is sometimes called a “Universal Crystal” because of its multipurpose uses and all of the broad connections to all chakras and all zodiac signs.
