Not a diamond; this specimen is visibly synthetic or treated quartz, commonly known as Aqua Aura or Mystic Quartz, created via chemical vapor deposition of metal oxides onto a natural or synthetic quartz crystal.
Not a diamond; this specimen is visibly synthetic or treated quartz, commonly known as Aqua Aura or Mystic Quartz, created via chemical vapor deposition of metal oxides onto a natural or synthetic quartz crystal. · Rough crystal / Modified faceted hexagonal prism form with irregular cut elements.
Not applicable for standard diamond grading; artisan-cut rough crystal form. Cut
Carat
Estimated at over 100 carats due to the large physical dimensions of the specimen, though density differs from diamond.
Color
Iridescent fancy multi-color coating displaying strong interference colors of blue, gold, and pink.
Clarity
Included (Contains prominent internal fractures, stress cracks, and surface irregularities typical of treated quartz crystals).
Shape
Rough crystal / Modified faceted hexagonal prism form with irregular cut elements.
Overall Assessment
The specimen is a striking example of an enhanced quartz crystal featuring an iridescent metallic coating, rather than a genuine diamond. Its visual appeal lies entirely in its vibrant play of rainbow interference colors and raw crystalline structure.
Cut Quality
Not applicable for standard diamond grading; artisan-cut rough crystal form.
Brilliance
Low to moderate white light return, heavily influenced by surface interference rather than internal refraction.
Fire
High surface dispersion caused by the thin metal oxide film rather than intrinsic material properties.
Scintillation
Flashes of iridescent rainbow colors moving across the coated faces under dynamic lighting.
Proportions
Non-standard proportions; large elongated crystal section with irregular depth and angles.
Symmetry
Asymmetrical, showing natural crystal habit combined with arbitrary flat facets.
Polish
Poor to fair, displaying visible surface grain, roughness, and coating residue rather than a high gem polish.
Fluorescence
Inert to faint, typical of coated quartz crystals under standard UV conditions.
Inclusions
Large feather fractures, internal fissures, and surface pitting.
Blemishes
Coating wear, scratches, and uneven surface application marks.
Origin
Synthetic or enhanced natural quartz, commonly processed in specialized laboratories or workshops.
Treatment Detection
Surface coating clearly visible under magnification, showing thin-film interference colors and localized flaking along stress points.
Estimated Value
Low commercial value ($20 to $100 USD) as a mineral specimen and novelty item.
Certification Estimate
Standard gemological laboratories (GIA, IGI) would issue a report identifying this as treated quartz (coater/enhancer applied) rather than a diamond report.
Investment Potential
Negligible; valued purely for decorative or aesthetic crystal collection purposes.
Similar Diamonds
None, as this is fundamentally a quartz crystal and possesses completely different physical and optical properties from any diamond.
Setting Suggestions
Wire-wrapped pendant settings or artisan bezel settings using sterling silver or antiqued copper to complement its raw crystal appearance.
Care & Maintenance
Avoid harsh chemical cleaners, ultrasonic baths, and abrasive surfaces which can strip or scratch the delicate metal oxide coating.
Interesting Facts
Aqua Aura and similar coated quartzes are produced by bonding vaporized gold, titanium, or other precious metals to the surface of quartz in a high-vacuum chamber.
