Carat
Estimated around 3.5 to 5.0 carats (based on scale relative to fingers)

Overall Assessment
The specimen shown in the image is a raw, green, crystalline or glassy fragment. It lacks the defining optical and physical properties of a diamond (such as extreme hardness, high dispersion, and adamantine luster) and is likely glass or a common green mineral.
Cut Quality
Uncut / Raw (Not applicable for a faceted diamond)
Brilliance
Low to moderate vitreous luster, typical of glass or low-grade crystal
Fire
Minimal to none, lacks high dispersion of diamond
Scintillation
Poor, due to lack of standard facet arrangement
Proportions
N/A for raw un-faceted stone
Symmetry
Asymmetrical raw stone
Polish
Unpolished / Raw surface texture with visible striations
Fluorescence
Cannot be definitively determined without UV testing, likely inert
Inclusions
Internal fracture planes, gas bubbles (if glass), and mineral inclusions
Blemishes
Surface scratches, chips, and irregular cleavage/fracture lines
Origin
Synthetic/Man-made glass slag or common mineral crystal
Treatment Detection
Likely colored glass or dyed mineral material
Estimated Value
Nominal / Low value (collector specimen or decorative glass piece, <$10)
Certification Estimate
Will not be certified by GIA, AGS, or IGI as a diamond
Investment Potential
None as an investment gemstone
Similar Diamonds
None, as this specimen lacks diamond properties entirely
Setting Suggestions
Wire-wrapping if used as a mineral specimen for jewelry
Care & Maintenance
Standard cleaning with warm soapy water and soft brush; avoid harsh chemicals
