Indeterminate - Likely non-gemstone material (Glass or Slag)
Indeterminate - Likely non-gemstone material (Glass or Slag) · Irregular/Uncut Rough fragment
Poor/Uncut Cut
Carat
Estimated 100+ carats based on visual scale
Color
Likely color-range of J-K (faint yellow/grey tint)
Clarity
Included/Industrial (I3 or lower)
Shape
Irregular/Uncut Rough fragment
Overall Assessment
This object does not display the structural or optical characteristics of a gem-grade diamond. It appears to be a large piece of industrial glass, slag, or a low-quality mineral fragment, lacking the crystal structure associated with diamond rough.
Cut Quality
Poor/Uncut
Brilliance
Low/Dull due to lack of faceting and transparency
Fire
Low - visible dispersive flashes are likely surface refraction from fractures
Scintillation
Low/Negligible
Proportions
N/A - Lacks geometric faceting for analysis
Symmetry
Poor/None
Polish
None/Natural rough surface
Fluorescence
Non-diagnostic from image
Inclusions
Extense internal fractures, veils, and heavy clouding
Blemishes
Chipped edges, uneven conchoidal fractures, and surface pitting
Origin
Potential industrial discard or common mineral specimen
Treatment Detection
No obvious gemological treatments; appears to be raw mass
Estimated Value
$10 - $50 (Decorative or mineral sample value)
Certification Estimate
Unlikely to be graded by GIA/AGS as a gemstone; requires basic mineral identification
Investment Potential
None - Lacks the quality, rarity, and clarity required for investment
Similar Diamonds
Uncut industrial bort or decorative glass cullet
Setting Suggestions
Not suitable for traditional jewelry setting; better as a display specimen
Care & Maintenance
Wipe with a damp cloth; avoid heavy impacts as internal fractures may cause the stone to shatter
Interesting Facts
The large size and high internal fracture density are typical of glass or low-quality mineral specimens rather than gem-quality carbon.
