Overall Assessment
The stone pictured is almost certainly not a diamond. Its cabochon cut, extreme transparency, and characteristic needle-like inclusions strongly indicate rutilated quartz, a popular semi-precious gemstone.
Cut Quality
N/A (Cabochon cuts do not receive diamond cut grades)
Brilliance
Very Low (Non-faceted surface leads to duller reflection)
Fire
None detected (No light dispersion)
Scintillation
None (Lacks facets to produce sparkle/scintillation)
Proportions
High dome, lacks a table or facets for traditional diamond proportion analysis
Symmetry
Good (Hand-cut appearance)
Polish
Good (High surface luster)
Fluorescence
Indeterminable via image
Inclusions
Long, needle-like rutilated inclusions (likely rutile or tourmaline needles) and internal clouds
Blemishes
Minor surface abrasions and contact marks consistent with a soft bezel setting
Origin
Likely natural quartz from Brazil or Africa
Treatment Detection
No obvious treatments, typical of natural rutilated quartz
Estimated Value
$50 - $150 (Commercial grade quartz jewelry)
Certification Estimate
Gemological lab (like GIA or IGI) would likely identify this as Rutilated Quartz, not Diamond
Investment Potential
Very Low (Considered a decorative or fashion gemstone)
Similar Diamonds
None (Diamonds are rarely cut in cabochons unless extremely low quality)
Setting Suggestions
Protective gold or silver bezel setting as currently shown
