Not applicable (Uncut rough fragment) Cut
Carat
Not applicable (Rough mineraloid/glass specimen, high mass)
Color
Colorless with slight greenish-blue tint
Clarity
Not applicable (Contains visible gas bubbles and internal fractures)
Shape
Raw, uncut, irregular fragment
Overall Assessment
The specimen shown is definitively not a diamond. Visual indicators such as conchoidal fracture patterns and internal bubbles point towards industrial glass or slag. It holds no gemological value as a diamond.
Cut Quality
Not applicable (Uncut rough fragment)
Brilliance
Low to moderate vitreous luster, not diamond brilliance
Fire
Minimal dispersion compared to diamond
Scintillation
Poor due to lack of standard facet arrangement
Proportions
Irregular raw specimen dimensions
Symmetry
Asymmetrical rough
Polish
Raw fractured surfaces, unpolished
Fluorescence
Unknown without UV testing
Inclusions
Conchoidal fractures, gas bubbles (indicating glass), and internal stress cracks
Blemishes
Surface scratches, chips, and irregular cleavage plains
Origin
Synthetic industrial byproduct (slag) or common quartz
Treatment Detection
None applied; raw material
Estimated Value
Minimal monetary value (decorative or educational specimen)
Certification Estimate
Not certifiable as a gemstone by major labs (GIA, AGS, IGI)
Investment Potential
None as an investment
Similar Diamonds
None (this specimen is not a diamond)
Setting Suggestions
Not recommended for fine jewelry due to softness and fragility
Care & Maintenance
Handle with care to avoid chipping, clean with mild soapy water
Interesting Facts
The presence of curved internal striations and bubbles strongly suggests this is manufactured glass rather than a natural gemstone rough.
