Natural (Rough green diamond, potentially irradiated or naturally colored)
Natural (Rough green diamond, potentially irradiated or naturally colored) · Rough crystal / Uncut crystal form
Not applicable (Rough stone) Cut
Carat
Estimated 3.5 - 5.0 carats
Color
Fancy Vivid Green
Clarity
Included (I1/I2 rough estimate)
Shape
Rough crystal / Uncut crystal form
Overall Assessment
An intriguing, deeply saturated green rough diamond crystal displaying natural growth features and surface texture. Professional gemological laboratory testing is essential to confirm whether the vibrant green color is of natural atomic origin or artificially induced.
Cut Quality
Not applicable (Rough stone)
Brilliance
Low due to rough surface and uncut state
Fire
Obscured by surface texture and heavy saturation
Scintillation
Minimal in current uncut, rough state
Proportions
Natural rough proportions, deep uncalibrated crystal
Symmetry
Natural octahedral/irregular crystal symmetry
Polish
Unpolished natural crystal faces (trigons may be present)
Fluorescence
Likely strong yellow or green (common in natural green diamonds)
Inclusions
Cloudy internal structures, feather fractures, and natural mineral inclusions
Blemishes
Rough surface pitting, natural indentation marks, and adhering matrix minerals
Origin
Natural rough diamond, possibly alluvial or kimberlite pipe origin
Treatment Detection
Advanced spectroscopic testing needed to rule out laboratory irradiation (common for green diamonds)
Estimated Value
Varies significantly depending on color origin; natural untreated vivid green can be extremely valuable, while laboratory-irradiated stones are considerably less.
Certification Estimate
GIA Colored Diamond Report (would require testing for natural vs. treated color origin)
Investment Potential
High risk/high reward depending entirely on laboratory verification of natural color origin
Similar Diamonds
Rough green diamond crystals from African or South American deposits
Setting Suggestions
Custom raw-stone bezel setting in yellow gold or platinum to protect the fragile edges
Care & Maintenance
Avoid harsh ultrasonic cleaners due to internal fractures and surface roughness; clean gently with warm soapy water
Interesting Facts
Green diamonds get their color naturally from exposure to radioactive radiation in the earth over millions of years, which displaces carbon atoms in the crystal lattice.
