Aqua Aura Quartz
Aqua Aura Quartz is coated quartz (vapor-deposited gold), SiO₂ + Au surface film. In the hand, it rates 7 (coating can wear) on the Mohs scale, and it runs electric sky blue with rainbow edges. Unnaturally electric blue quartz whose color lives on the surface, chipped spots show colorless quartz beneath.
The geology.
Aqua Aura Quartz carries the formula SiO₂ + Au surface film. It belongs to the trigonal (quartz substrate) system. Catalogues list it as coated quartz (vapor-deposited gold).
It sits at 7 (coating can wear) on the Mohs scale. The surface reads vitreous with metallic-blue sheen. Light behaviour is transparent with surface color. Specific gravity runs 2.65. The streak is white. It breaks with conchoidal fracture.
Unnaturally electric blue quartz whose color lives on the surface, chipped spots show colorless quartz beneath.
It reaches buyers as points, clusters, beads or pendants.
The origins.
Natural quartz coated with vaporized gold in vacuum chambers (USA, China).
On value, the database notes: affordable.
Traditional associations.
In energy work traditions, marketed for calm expression, the blue is a man-made gold coating on real quartz.
We keep this section because people ask. It sits below the geology on purpose, and none of it describes something the stone does.
Spotting the real thing.
Unnaturally electric blue quartz whose color lives on the surface, chipped spots show colorless quartz beneath.
It is a treatment by definition; the issue is sellers presenting it as naturally blue crystal.
| Looks like | How to tell them apart |
|---|---|
| Blue topaz | Topaz color is body color throughout, not a surface film |
| Natural blue quartz | Natural blue quartz is hazy gray-blue from inclusions, never electric |
| Angel aura quartz | Angel aura is pastel rainbow; aqua aura is saturated blue |
At-home tests.
Before anyone talks you into a lab report, these are the checks worth doing yourself on aqua aura quartz.
| Test | What you should see |
|---|---|
| By eye | Inspect chips and drill holes for colorless interior |
| By eye | Surface iridescence with metallic flash at edges |
| Quartz hardness | scratches glass |
Destructive tests belong to a gemologist, not a kitchen table. If a piece matters to you, pay for an appraisal before you take a file to it.
Care & handling.
At 7 (coating can wear) on the Mohs scale it stands up to everyday wear. It will still chip on a hard knock, so treat edges and points with respect.
It breaks with conchoidal fracture, which is worth knowing before you set it or drop it.
Clean it by hand, dry it properly, and keep it away from ultrasonic cleaners and hot steam.

What it is worth
Affordable.
Where buyers get caught
It is a treatment by definition; the issue is sellers presenting it as naturally blue crystal.
One more thing
The electric blue comes from an ultra-thin layer of actual gold, the same physics that makes soap bubbles colorful.
