Not a diamond; visual indicators reveal this to be green glass / slag or potentially synthetic green quartz/yttrium aluminum garnet due to internal spherical gas bubbles visible under magnification.

Not applicable (Raw/Uncut material with partial window polish) Cut
Carat
Not applicable for synthetic glass simulation (approx. 15-20 carats by volume equivalent if measured)
Color
Fancy Vivid Green (Simulated)
Clarity
Included (Contains prominent gas bubbles and swirling flow lines characteristic of glass)
Shape
Irregular raw nodule / tumbled fragment with a polished window facet
Overall Assessment
This specimen is decisively identified as a green glass or simulated material, exhibiting classic diagnostic features such as internal gas bubbles and conchoidal fractures, completely negating any classification as a natural or lab-grown diamond.
Cut Quality
Not applicable (Raw/Uncut material with partial window polish)
Brilliance
Low due to lower refractive index compared to diamond (RI ~1.50 vs diamond 2.42)
Fire
Very low dispersion compared to diamond
Scintillation
Poor, lacks the sharp light return and dark contrast patterns of a diamond
Proportions
Non-standard custom window cut, lacking standard facet geometry
Symmetry
Not applicable
Polish
Poor to fair on the cut window, rough matte texture elsewhere
Fluorescence
Inert to strong depending on UV wavelength, typical of certain colorants in glass
Inclusions
Numerous spherical gas bubbles and internal swirls
Blemishes
Surface pitting, abrasion marks, and conchoidal fracture ripples
Origin
Man-made / Industrial or decorative glass production
Treatment Detection
Colored glass composition; no diamond treatments applicable
Estimated Value
Nominal decorative or collector value (less than $10 USD)
Certification Estimate
Not certifiable as a gemstone by major labs like GIA or AGS (would be identified as glass)
Investment Potential
None as a gemstone or investment asset
Similar Diamonds
None, as this is visually and compositionally glass rather than diamond
Setting Suggestions
Not recommended for fine jewelry due to softness and lack of durability
Care & Maintenance
Store separately to prevent scratching softer materials, clean with mild soapy water
Interesting Facts
Green glass and slag are frequently mistaken for rough emeralds, peridot, or green diamonds by novices due to their vivid coloration and presence in nature as industrial waste or sea glass.
