Not a diamond; appears to be raw green glass or slag, possibly quartz/tourmaline simulant
Not a diamond; appears to be raw green glass or slag, possibly quartz/tourmaline simulant · Rough / Raw irregular fragment
Not Applicable (uncut rough material) Cut
Carat
Estimated 4.0 - 6.0 carats based on visual size
Color
Fancy Vivid Green (Simulated/Glass)
Clarity
Included (contains flow lines and bubbles typical of glass)
Shape
Rough / Raw irregular fragment
Overall Assessment
This specimen is visually identified as green glass rather than a genuine diamond or precious gemstone. It displays characteristic conchoidal fracture lines and lacks the extreme hardness, refractive index, and optical properties of diamond.
Cut Quality
Not Applicable (uncut rough material)
Brilliance
Vitreous luster typical of glass
Fire
Very low dispersion compared to diamond
Scintillation
Low to moderate due to raw amorphous surface
Proportions
Not Applicable
Symmetry
Not Applicable
Polish
Unpolished natural/raw surface with conchoidal fractures
Fluorescence
Unknown / Not tested under UV
Inclusions
Conchoidal fracture lines, possible gas bubbles typical of manufactured glass
Blemishes
Surface chips and striations from breaking
Origin
Synthetic / Man-made glass or slag
Treatment Detection
Colored glass simulants do not undergo diamond enhancement treatments
Estimated Value
Nominal / Low value as a mineral specimen or craft material (<$10)
Certification Estimate
Gemological laboratories would not issue a diamond grading report for this material
Investment Potential
None; glass has no resale or investment value as a gemstone
Similar Diamonds
None, as this is a glass simulant and not a diamond
Setting Suggestions
Wire-wrapped or bezel setting if used for artisan jewelry
Care & Maintenance
Avoid harsh impacts as glass is brittle and prone to chipping; clean with mild soapy water
Interesting Facts
Bright green glass is frequently mistaken for rough emerald, peridot, or green diamond by untrained observers due to its striking color and conchoidal fracture patterns.
