Aura Quartz Geodes (Lab-Altered)
Silicon Dioxide (SiO2) with Metallic Vapor Deposition
Rock Type: mineral

Physical Properties
Hardness: 7 Mohs; Color: Iridescent, teal, purple; Luster: Vitreous to metallic; Crystal structure: Hexagonal/Trigonal; Specific Gravity: 2.65.
Formation & Geological History
Natural quartz geodes are formed in volcanic or sedimentary cavities. These specific specimens have undergone a modern lab process called vacuum deposition to bond metal vapors (like gold, titanium, or cobalt) to the surface.
Uses & Applications
Primarily used for home decor, crystal healing, collection, and jewelry. The bright colors make them popular in metaphysical shops.
Geological Facts
While the base quartz is natural, the vibrant 'aura' colors are man-made. The purple and teal hues are achieved by bonding fuming metals to the quartz at high temperatures in a vacuum.
Field Identification & Locations
Identify by the extreme neon or iridescent colors which do not occur naturally in these specific combinations in raw quartz. Often found at gem shows and 'metaphysical' retail stores.
