Not a diamond; this specimen appears to be treated quartz or glass featuring an iridescent coating or optical interference effects.
Not a diamond; this specimen appears to be treated quartz or glass featuring an iridescent coating or optical interference effects. · Irregular faceted or cut crystal form, not a standard diamond shape.
Fair to Poor (Hand-carved or crudely faceted with uneven proportions). Cut

Carat
Not applicable; gemstone/mineral specimen rather than standard cut diamond.
Color
Fancy multi-color/iridescent display due to surface treatment.
Clarity
Included (Contains prominent internal fractures, stress lines, and surface irregularities).
Shape
Irregular faceted or cut crystal form, not a standard diamond shape.
Overall Assessment
The specimen displayed is definitively not a diamond. Visual analysis confirms it is an altered mineral crystal (likely quartz or glass) featuring an applied iridescent surface coating and significant internal fractures.
Cut Quality
Fair to Poor (Hand-carved or crudely faceted with uneven proportions).
Brilliance
Low brilliance, hindered by internal fractures and cloudy matrix.
Fire
Artificial spectral dispersion enhanced by surface coating rather than true internal dispersion.
Scintillation
Limited and patchy sparkle due to irregular facets and surface treatment.
Proportions
Non-standard proportions with varying depth and angles uncharacteristic of precision diamond cutting.
Symmetry
Poor symmetry with irregular facet alignments.
Polish
Fair polish, showing visible abrasions and tool marks.
Fluorescence
Cannot be definitively determined without UV testing, though likely inert or showing weak surface reflections.
Inclusions
Prominent internal feathers, gas bubbles, and stress fractures.
Blemishes
Surface scratches, pits, and residue from coating processes.
Origin
Likely manufactured or heavily treated mineral specimen.
Treatment Detection
Clear visual evidence of surface coating (often titanium or metal oxide vapor deposition to create an iridescent aura effect).
Estimated Value
Nominal decorative or mineral specimen value (low monetary value compared to genuine gemstones).
Certification Estimate
Standard gemological laboratories (GIA, IGI) would issue a report identifying it as treated quartz or glass, not a diamond.
Investment Potential
Negligible investment or resale value; valued strictly for aesthetic or educational curiosity.
Similar Diamonds
None; this specimen shares no characteristics with gem-quality diamonds.
Setting Suggestions
Wire-wrapping or bespoke artisan bezel settings suitable for rough or novelty mineral specimens.
Care & Maintenance
Avoid harsh chemicals, ultrasonic cleaners, and abrasive surfaces which could damage the delicate surface coating.
Interesting Facts
Coated quartz items are often marketed commercially under trade names like 'aura quartz' or 'mystic quartz', created by bonding vaporized metals to natural quartz crystals at high temperatures.
