Not a diamond; this specimen is green glass showing characteristic spherical gas bubbles. · Rough/uncut broken chunk with irregular contours.
Not applicable (raw, unfaceted glass fragment). Cut
Carat
Not applicable for glass; weight cannot be accurately estimated visually without density testing.
Color
Fancy intense green (simulated).
Clarity
Included due to abundant internal gas bubbles and flow lines.
Shape
Rough/uncut broken chunk with irregular contours.
Overall Assessment
The specimen is clearly identified as green glass based on the presence of internal gas bubbles and conchoidal fracture lines, possessing no diamond characteristics.
Cut Quality
Not applicable (raw, unfaceted glass fragment).
Brilliance
Low to moderate vitreous luster.
Fire
Very low dispersion compared to diamond.
Scintillation
Poor due to lack of standard facet arrangement.
Proportions
Not applicable (raw fragment).
Symmetry
Asymmetrical, irregular fracture.
Polish
Unpolished, rough fracture surfaces with conchoidal texture.
Fluorescence
Indeterminate without UV testing, though common in some colored glass.
Inclusions
Numerous spherical gas bubbles visible throughout the matrix, typical of manufactured glass.
Blemishes
Surface scratches, chipped edges, and conchoidal fracture ripples.
Origin
Man-made/synthetic glass product.
Treatment Detection
Not applicable as it is not a genuine gemstone.
Estimated Value
Nominal/decorative value only (negligible gemological value).
Certification Estimate
Cannot be certified by gemological diamond labs (GIA, AGS, IGI) as a diamond; would be identified as man-made glass.
Investment Potential
None.
Similar Diamonds
None, as this material is glass rather than diamond.
Setting Suggestions
Not recommended for fine jewelry due to low hardness and durability.
Care & Maintenance
Store separately to avoid scratching softer materials; clean with mild soapy water.
Interesting Facts
Green glass is frequently mistaken for rough emerald or green diamond by novices, but internal gas bubbles are a dead giveaway for glass.
