Likely Quartz or Glass Simulant
Likely Quartz or Glass Simulant · Rough/Broken Fragment
Poor/Ungraded (Fragmentary) Cut

Carat
Estimated 10.0-20.0 carats (based on scale)
Color
Near-colorless to Faint Gray
Clarity
I3 (Significant internal fractures and heavy inclusions)
Shape
Rough/Broken Fragment
Overall Assessment
This specimen is not a faceted diamond. It lacks the refractive index, luster, and cleavage patterns of a diamond, appearing instead to be a fragment of quartz or glass.
Cut Quality
Poor/Ungraded (Fragmentary)
Brilliance
Very Low (Due to lack of professional faceting)
Fire
None visible
Scintillation
Low (Muted light return)
Proportions
Non-standard (Lacks geometric symmetry)
Symmetry
Poor (Asymmetrical/Broken)
Polish
Poor (Significant surface abrasions)
Fluorescence
None visible
Inclusions
Extensive internal cleavage planes and fracture lines
Blemishes
Chipped edges and surface pitting
Origin
Likely terrestrial mineral (Earth-mined quartz)
Treatment Detection
None detected; appears in a raw, weathered state
Estimated Value
$1 - $20 (Material appears to be industrial grade or non-diamond mineral)
Certification Estimate
Unlikely to be certified by GIA/AGS as a gemstone
Investment Potential
Zero; this is not a gemstone-quality specimen
Similar Diamonds
None; more comparable to industrial quartz or slag glass
Setting Suggestions
Not suitable for traditional jewelry settings
Care & Maintenance
Handle with care as the sharp edges and fractures may cause the stone to crumble
Interesting Facts
The conchoidal fracturing seen is more characteristic of glass or quartz than the octahedral cleavage of a diamond
