Not a diamond; this is a rough green glass or slag material exhibiting conchoidal fracture and internal flow lines.
Not a diamond; this is a rough green glass or slag material exhibiting conchoidal fracture and internal flow lines. · Rough, unpolished raw fragment with irregular shape
Not applicable (raw, uncut material) Cut

Carat
Not applicable as this is glass, but visually estimated at roughly 15-20 carats equivalent volume
Color
Deep vivid green (fancy intense green appearance, though material is glass)
Clarity
Not applicable for glass; contains numerous internal bubbles, flow lines, and debris
Shape
Rough, unpolished raw fragment with irregular shape
Overall Assessment
This specimen is a raw piece of green glass showing typical conchoidal fractures and internal bubbles, possessing no gemological relation to diamond.
Cut Quality
Not applicable (raw, uncut material)
Brilliance
Vitreous to glassy reflection, limited brilliance due to lack of standard facet proportions
Fire
Very low dispersion compared to diamond
Scintillation
Poor scintillation due to lack of precise faceting and high internal inclusion density
Proportions
Not applicable to raw unstructured material
Symmetry
Asymmetrical raw fragment
Polish
Unpolished, rough fracture surfaces with glassy luster
Fluorescence
Unknown without UV testing, typical green glass may show inert or moderate fluorescence
Inclusions
Gas bubbles, swirl marks, and internal striations characteristic of manufactured glass
Blemishes
Surface chips and conchoidal fracture marks
Origin
Man-made glass or industrial slag
Treatment Detection
Colored glass composition; no diamond treatments applicable
Estimated Value
Nominal decorative or specimen value (very low, less than $10)
Certification Estimate
Cannot be certified as a diamond; would be identified as glass by any standard gemological laboratory (GIA, IGI, etc.)
Investment Potential
None as an investment
Similar Diamonds
None, as this is visually and compositionally glass rather than diamond
Setting Suggestions
Not recommended for fine jewelry due to softness and fragile nature
Care & Maintenance
Handle with care to avoid chipping; clean with mild soapy water
Interesting Facts
Green glass is frequently mistaken for rough emerald, peridot, or green diamond by untrained observers due to its vibrant color.
