Indeterminate / Simulant Suspect
Indeterminate / Simulant Suspect · Irregular Slice / Rough Fragment
None (Rough/Uncut) Cut
Carat
Estimated 2.0 - 4.0 carats based on physical size
Color
Grayish-White with brownish undertones
Clarity
Included (I2-I3) / Opaque
Shape
Irregular Slice / Rough Fragment
Overall Assessment
The specimen appears to be a fragment of quartz, glass, or low-grade industrial mineral rather than a gem-quality diamond. It lacks the refractive index and crystal structure associated with diamond.
Cut Quality
None (Rough/Uncut)
Brilliance
Very Low (Minimal light return)
Fire
None detected
Scintillation
Weak surface luster (Greasy/Vitreous)
Proportions
N/A (Non-geometric form)
Symmetry
Poor (Asymmetrical rough)
Polish
N/A (Natural surface/Fractured)
Fluorescence
Undetermined without UV light
Inclusions
Heavy internal fracturing, cloudiness, and mineral veining
Blemishes
Surface abrasions, pits, and jagged fracture edges
Origin
Alluvial or primary source rock (Possible Quartz or Glass)
Treatment Detection
None visible; appears to be raw material
Estimated Value
$10 - $100 (Specimen value only, assuming non-gem quality)
Certification Estimate
Unlikely to be certified by GIA/AGS in current state
Investment Potential
None; specimen appears to be of mineralogical rather than gemological interest
Similar Diamonds
Industrial grade rough or boart
Setting Suggestions
Wire wrap or rough-stone artisan pendant
Care & Maintenance
Avoid impact; clean with soft brush and soapy water
Interesting Facts
The specimen lacks the octahedral crystal habit typical of natural diamonds
