Aura Quartz clusters are beautiful crystal formations that have been treated with a thin layer of precious metals, usually titanium or other elements, through a process called "vacuum metal deposition." This treatment creates a stunning iridescent or rainbow-like sheen on the surface of the crystals, giving them their unique and captivating appearance.
 
The base crystals used for these aura quartz clusters are clear quartz, although other varieties of quartz can also be used. The thin metal coating enhances the crystal's natural properties and creates a shimmering effect, reflecting a beautiful array of colors when light interacts with the surface.
 
Aura Quartz clusters are not only admired for their appearance but are also believed to possess metaphysical properties and spiritual energies associated with clear quartz. The addition of the metallic coating is thought to enhance and amplify the crystal's energy, making it popular among crystal enthusiasts, energy healers, and collectors.
