Metal-coated crystals “Aura” are natural crystals, such as quartz, whose surface has been coated with metal to give them an iridescent metallic sheen. Crystals treated this way are used as gemstones and for other decorative purposes. Possible coatings include gold (resulting in a stone called aqua aura), indium, titanium, niobium and copper. Other names for crystals treated so include; angel aura, flame aura, opal aura or rainbow quartz.

For example: Aqua aura is created in a vacuum chamber from quartz crystals and gold vapor by vapor deposition. The quartz is heated to 871 °C (1600 °F) in a vacuum, and then gold vapor is added to the chamber. The gold atoms fuse to the crystal’s surface, which gives the crystal an iridescent metallic sheen.

The aura covers quartz from Arkansas.
