Not applicable (Uncut, raw fracture) Cut
Carat
Not applicable (Rough glass material)
Color
Olive-yellow / Amber tinted glass
Clarity
Not applicable (Contains bubbles and inclusions typical of manufactured glass)
Shape
Irregular raw / Rough fragment
Overall Assessment
The specimen shown in the image is not a diamond, but rather a piece of colored glass or industrial slag featuring sharp conchoidal fracture surfaces and internal bubbles.
Cut Quality
Not applicable (Uncut, raw fracture)
Brilliance
Low to moderate vitreous luster
Fire
Very low dispersion compared to diamond
Scintillation
Poor due to lack of facets
Proportions
Not applicable
Symmetry
Asymmetrical raw fragment
Polish
Unpolished natural fracture surface
Fluorescence
Unknown without UV testing
Inclusions
Gas bubbles and internal flow lines visible, typical of glass
Blemishes
Surface scratches, chips, and conchoidal fracture ripples
Origin
Man-made glass / Industrial slag
Treatment Detection
Colored glass showing characteristic melt features
Estimated Value
Minimal / Negligible monetary value as a gemstone
Certification Estimate
Not certifiable as a gemstone by standard gemological labs (GIA, AGS, IGI)
Investment Potential
None
Similar Diamonds
None (Glass is easily distinguished from diamond by hardness and thermal conductivity)
Setting Suggestions
Not recommended for jewelry settings due to low durability
Care & Maintenance
Handle with care to avoid cuts from sharp glass edges
Interesting Facts
Conchoidal fractures in glass closely mimic the fracture patterns found in some rough minerals, often leading to mistaken identity.
