Green Colored Diamond (Natural / Treated)
Green Colored Diamond (Natural / Treated) · Rough / Uncut Crystal
Not Applicable (Rough crystal specimen) Cut
Carat
Estimated 2.5 - 3.5 carats based on rough crystal dimensions
Color
Fancy Vivid Green
Clarity
SI1 - SI2 (Visible internal growth structures and natural surface features)
Shape
Rough / Uncut Crystal
Overall Assessment
An intriguing vibrant green rough diamond specimen with prominent natural growth lines (triangles/striations) on the surface, offering significant potential for custom lapidary work or as a collector's mineral specimen.
Cut Quality
Not Applicable (Rough crystal specimen)
Brilliance
Limited due to rough surface, though high refractive index is apparent
Fire
Subdued dispersion across raw crystal planes
Scintillation
Flashes of light reflect off natural crystal faces and internal cleavage planes
Proportions
Not Applicable (Uncut rough stone)
Symmetry
Natural asymmetric crystal growth form (Octahedral/Trigonal distortion)
Polish
Natural rough crystal faces (trigons and striations visible)
Fluorescence
Medium to Strong Yellowish-Green (typical for many natural green diamonds)
Inclusions
Internal graining, natural crystal clouds, and feather fractures visible
Blemishes
Natural etch channels, growth lines, and rough surface texture
Origin
Alluvial deposit or primary kimberlitic pipe; commonly associated with radiation exposure in geological history
Treatment Detection
Potential surface irradiation or laboratory HPHT/irradiation treatment to enhance green coloration (requires advanced spectroscopy to confirm)
Estimated Value
$5,000 - $15,000 depending on final cut potential and official origin/treatment report
Certification Estimate
GIA Colored Diamond Report (Expected confirmation of natural vs irradiation treatment)
Investment Potential
High speculative value if certified as a rare naturally irradiated green diamond, especially if cut to maximize color saturation
Similar Diamonds
Natural green rough diamonds from Democratic Republic of Congo or South American deposits
Setting Suggestions
Custom bezel setting or prong mounting designed to showcase the raw crystal morphology, paired with yellow or white gold
Care & Maintenance
Avoid harsh ultrasonic cleaners due to internal feather inclusions; clean gently with warm soapy water and a soft brush
Interesting Facts
Natural green diamonds get their color when radiation from radioactive rocks alters the crystal lattice over millions of years
