Aura Quartz Geode (specifically Rose Aura or Magenta Aura)
Quartz var. Treated Quartz (Silicon Dioxide with metal coating) · Decorative Stone / Enhanced Mineral Specimen
Crystal System
Trigonal system, commonly forming as a hollow geode lined with microcrystalline or macrocrystalline quartz druzy.
Mineral Group
Silicates (Subgroup: Tectosilicates)
Chemical Formula
SiO2 (Core mineral) bonded with vaporized precious metals (typically Gold and Titanium)
Formation Process
The base quartz forms via hydrothermal or volcanic processes in gas cavities. The aura treatment is an artificial enhancement applied in a vacuum chamber where the quartz is heated to high temperatures and bonded with vaporized metal atoms.
About This Crystal
This specimen is a small quartz geode fragment featuring an inner cavity lined with tiny quartz points. It displays a vibrant, iridescent, metallic-sheen coating in shades of hot pink, magenta, and golden-yellow. The exterior host rock is typically covered or cut, while the treated interior exhibits a high-luster, rainbow-like metallic gloss.
Physical Characteristics
Base mineral hardness 7 on the Mohs scale, though the metallic coating may be susceptible to scratching. White streak, conchoidal fracture, vitreous to metallic luster on the coated surfaces, specific gravity of approximately 2.65 for the base quartz.
Optical Properties
Singly or doubly refractive for the base quartz, modified by a strong surface thin-film interference effect producing metallic iridescence and play-of-color across the coated faces.
Hardness & Durability
Origin Region
The base quartz typically originates from Brazil, Morocco, or the United States, and is treated in laboratories primarily in the USA.
Hardness & Durability
Mohs hardness of 7 for the underlying quartz, but the bonded metal coating can be damaged by harsh abrasives or acidic cleaners.
Care & Maintenance
Clean gently with warm, soapy water and a soft cloth. Avoid ultrasonic cleaners, steam cleaning, harsh chemicals, and prolonged exposure to abrasive surfaces which could wear off the metallic coating.
Rarity & Value
Common; base quartz geodes are widely available, and the value is affordable to moderate, driven primarily by the novelty and aesthetic appeal of the metallic aura treatment.
Special Characteristics
Exhibits intense thin-film interference colors (iridescence/aurachroming) created by the molecular bonding of precious metals to the quartz surface.
Lore & History
A modern creation with no ancient historical significance. In contemporary crystal healing and New Age practices, aura quartz is believed to elevate one's mood, cleanse the aura, stimulate the chakras, and promote inner peace and vitality, though these are traditional beliefs and not scientifically proven.
