Not a diamond; this specimen appears to be green glass or synthetic slag, displaying characteristic curved striae and gas bubbles.
Not a diamond; this specimen appears to be green glass or synthetic slag, displaying characteristic curved striae and gas bubbles. · Raw, unpolished, irregular fragment or chunk
Not applicable (Rough / Uncut) Cut
Carat
Cannot be precisely determined visually without specific density testing, but visually substantial as a rough chunk
Color
Vivid Green (Fancy Intense Green appearance, though artificial in origin)
Clarity
Not applicable to diamond grading; contains abundant round gas bubbles and flow lines characteristic of glass
Shape
Raw, unpolished, irregular fragment or chunk
Overall Assessment
Gemological inspection confirms this is an imitation material (glass) containing diagnostic gas bubbles and flow lines, rather than a genuine diamond or precious gemstone.
Cut Quality
Not applicable (Rough / Uncut)
Brilliance
Vitreous reflection typical of glass
Fire
Low to none; dispersion is minimal compared to diamond or high-RI simulants
Scintillation
Reflective pattern typical of fractured glass surfaces
Proportions
Not applicable
Symmetry
Not applicable (Irregular raw chunk)
Polish
Rough fracture surfaces with vitreous luster
Fluorescence
Unknown without UV testing
Inclusions
Numerous spherical gas bubbles and curved striations typical of manufactured glass
Blemishes
Surface flow lines, conchoidal fractures, and chips
Origin
Man-made / Manufactured glass
Treatment Detection
Material is entirely manufactured; no natural gemological treatments detected
Estimated Value
Minimal / Decorative value only (low-cost glass material)
Certification Estimate
Cannot be certified as a gemstone by major diamond labs (GIA, AGS, IGI); would be identified as glass upon gemological testing
Investment Potential
None as a gemstone or investment asset
Similar Diamonds
None; this material does not share physical or optical properties with diamonds
Setting Suggestions
Not recommended for fine jewelry settings due to low durability and non-gem status
Care & Maintenance
Handle with care to avoid chipping; keep away from harsh chemicals
Interesting Facts
Green glass is frequently mistaken for rough emerald, green diamond, or green tourmaline by untrained observers due to its vibrant color
