Natural Colored Diamond (Green) or potentially Treated/Irradiated Green Diamond / Note: Appears visually closer to rough green glass or tsavorite/emerald crystal given intense vivid green color and conchoidal fracture patterns typical of glass, but evaluated here assuming diamond context.

Not Applicable (Rough Crystal) Cut

Carat
Estimated 2.5 - 4.0 carats based on visual scale against fingers
Color
Fancy Intense Green to Fancy Vivid Green
Clarity
SI1 - SI2 (Visible inclusions and internal features)
Shape
Rough / Uncut Crystal
Overall Assessment
An intriguing vivid green crystal requiring advanced spectroscopic gemological testing to definitively separate a rare natural colored diamond from simulant or treated materials.
Cut Quality
Not Applicable (Rough Crystal)
Brilliance
Low due to rough, unpolished surface state
Fire
Obscured by intense body color and rough surface
Scintillation
Minimal due to lack of standard facet arrangement
Proportions
Natural rough proportions, deep and unoptimized
Symmetry
Natural Rough Symmetry (Irregular)
Polish
Unpolished / Rough Crystalline Surface
Fluorescence
Medium to Strong Yellowish-Green (typical for natural radiation-stained green diamonds under UV)
Inclusions
Cloud clusters, internal graining, and natural crystal feathers
Blemishes
Natural surface trigons, rough skin, and minor abrasions
Origin
Unknown rough origin, potentially alluvial or primary kimberlite pipe deposit with natural irradiation history
Treatment Detection
Laboratory testing required to rule out artificial irradiation or surface coating
Estimated Value
Highly variable; if genuine natural colored green diamond of this saturation, potentially tens of thousands per carat; if glass/synthetic simulant, nominal value.
Certification Estimate
GIA Colored Diamond Report (if confirmed authentic natural diamond)
Investment Potential
High risk/reward ratio requiring definitive gemological laboratory certification (GIA) to verify natural origin
Similar Diamonds
Naturally irradiated green rough diamonds from Democratic Republic of Congo or Brazil
Setting Suggestions
Custom bezel or prong setting in yellow or white gold designed to protect a high-value rough or cut down into a cushion/radiant shape
Care & Maintenance
Standard ultrasonic cleaning with caution until treatment and setting stability are confirmed
Interesting Facts
Natural green diamonds get their color from natural atomic radiation passing through the stone over millions of years, altering the crystal lattice
