Overall Assessment
The specimen shown in the image is definitively not a diamond. It exhibits optical and physical properties—such as conchoidal fracture lines and vitreous luster—consistent with colored glass or a gemstone simulant.
Cut Quality
Not applicable (raw/uncut shard)
Brilliance
Varies due to material properties, primarily vitreous luster
Fire
Very low, consistent with glass rather than diamond
Scintillation
Minimal, reflecting surface light rather than internal dispersion
Proportions
Irregular, no standard table or depth proportions
Symmetry
Asymmetrical irregular fragment
Polish
Unpolished natural fracture surfaces
Fluorescence
Unable to determine without UV testing
Inclusions
Gas bubbles and flow lines characteristic of glass
Blemishes
Surface scratches, chips, and conchoidal fracture marks
Origin
Man-made glass or synthetic simulant
Treatment Detection
Colored glass composition with typical manufacturing characteristics
Estimated Value
Nominal/decorative value only (minimal commercial value)
Certification Estimate
Cannot be certified by major diamond labs like GIA or IGI as a diamond
Investment Potential
None
Similar Diamonds
None, as this is visually identified as glass, not diamond
Setting Suggestions
Not recommended for fine jewelry due to softness and fragility
Care & Maintenance
Handle with care to avoid chipping the fragile edges; keep away from harsh chemicals
Interesting Facts
Green glass is frequently mistaken for rough emerald or green diamond due to its vivid color and conchoidal fracture pattern.
