Non-diamond (Glass or Slag)
Non-diamond (Glass or Slag) · Rough/Amorphous
None (Rough/Uncut) Cut

Carat
Unknown (Estimated 2-5 carats by volume)
Color
Colorless/Near-colorless with artificial dispersion
Clarity
Included/Translucent
Shape
Rough/Amorphous
Overall Assessment
The specimen is not a diamond. It lacks the cubic crystal lattice and 10 Mohs hardness indicators of diamond, showing instead the amorphous structure and fracture patterns of glass or slag.
Cut Quality
None (Rough/Uncut)
Brilliance
Low (Internal reflection consistent with low refractive index)
Fire
Visible in localized areas due to prismatic edges, not diamond-like
Scintillation
Poor (Lacks structural light return)
Proportions
N/A (No geometric facets)
Symmetry
N/A (Asymmetrical)
Polish
N/A (Rough texture)
Fluorescence
Inconclusive from image
Inclusions
Conchoidal fractures and flow lines characteristic of glass
Blemishes
Surface pitting and jagged edges
Origin
Likely industrial waste or glass fragment
Treatment Detection
Material appears to be a manufactured glass or slag by-product
Estimated Value
Negligible/Nominal
Certification Estimate
Unlikely to be graded by GIA/AGS as a gemstone; possible identification report as synthetic glass or slag
Investment Potential
None
Similar Diamonds
None; characteristics differ significantly from raw diamond carbon structures
Setting Suggestions
Not recommended for fine jewelry; wire-wrapping for novelty use only
Care & Maintenance
Handle with care as glass fragments can be sharp and brittle
Interesting Facts
The wavy flow lines and conchoidal fractures are classic diagnostic indicators used to differentiate glass from crystalline minerals like diamond.
