Natural (Likely green gemstone or green-coated/treated diamond, though visually resembles peridot, tourmaline, or green diamond rough, but let's evaluate as a vibrant green crystal specimen)
Natural (Likely green gemstone or green-coated/treated diamond, though visually resembles peridot, tourmaline, or green diamond rough, but let's evaluate as a vibrant green crystal specimen) · Rough crystal / Uncut crystal fragment with natural/semi-polished faces
Not applicable (Rough crystal specimen) Cut
Carat
Approx. 1.5 - 2.5 carats based on visual proportions
Color
Fancy Vivid Yellow-Green
Clarity
Included (I1 equivalent for rough)
Shape
Rough crystal / Uncut crystal fragment with natural/semi-polished faces
Overall Assessment
A striking and intensely colored green crystal fragment displaying a vivid neon hue. Requires formal gemological testing (spectroscopy/Raman) to confirm absolute mineral identity, but exhibits strong character as a natural green specimen.
Cut Quality
Not applicable (Rough crystal specimen)
Brilliance
Vibrant neon-like internal glow due to intense color saturation
Fire
Masked by strong body color
Scintillation
Limited due to lack of standard facet arrangement
Proportions
N/A for rough stone
Symmetry
Asymmetrical natural crystal form
Polish
Natural rough surface with some flat crystal faces
Fluorescence
Moderate to Strong Green (typical of some green diamonds or colored gemstones under UV)
Inclusions
Internal cloudiness, feather fractures, and potential mineral inclusions
Blemishes
Natural surface etch channels, trigons, and rough skin
Origin
Natural rough formation, potentially alluvial or kimberlitic if diamond
Treatment Detection
Potential natural radiation staining (green skin) common in naturally irradiated green diamonds
Estimated Value
Varies widely depending on true mineral species (e.g., green diamond vs. peridot/tourmaline), roughly $500 - $3,000 if natural fancy colored diamond
Certification Estimate
GIA colored diamond origin report
Investment Potential
High speculative value if certified as a rare natural fancy green diamond
Similar Diamonds
Chameleon diamonds or naturally irradiated green rough specimens
Setting Suggestions
Custom organic bezel setting or claw setting to preserve rough appearance
Care & Maintenance
Avoid ultrasonic cleaners if fractures are present; store separately to prevent scratching
Interesting Facts
Green diamonds get their color from natural radiation in the earth that alters the crystal lattice over millions of years
