Natural rough diamond crystal showing distinct trigons and natural surface textures
Natural rough diamond crystal showing distinct trigons and natural surface textures · Rough uncut octahedral/irregular crystal formation
Not applicable (rough, uncut stone) Cut
Carat
Estimated 2.5 - 4.0 carats based on physical dimensions relative to human fingers
Color
Near-colorless to faint yellow hue (approximately K-M range)
Clarity
Included (I1-I2) due to internal stress fractures and dark mineral inclusions
Shape
Rough uncut octahedral/irregular crystal formation
Overall Assessment
An interesting, tactile specimen of a natural rough diamond crystal with visible growth lines and inclusions, offering potential for a unique custom-cut gem or collection display
Cut Quality
Not applicable (rough, uncut stone)
Brilliance
Low in rough state; will improve significantly upon cutting and polishing
Fire
Obscured by rough surface textures and natural skin
Scintillation
Minimal in current rough form
Proportions
Natural rough proportions, requires professional mapping for optimal cutting yield
Symmetry
Natural crystal symmetry showing distorted octahedral growth
Polish
Natural unpolished crystal faces with typical growth features (trigons)
Fluorescence
Unknown without UV testing, likely medium blue if fluorescent
Inclusions
Heavy internal feathers, clouds, and dark carbon spots visible
Blemishes
Natural surface pitting, etch channels, and rough skin
Origin
Likely alluvial or primary kimberlite pipe origin from an African or Canadian source
Treatment Detection
Untreated natural rough diamond with original skin intact
Estimated Value
Varies widely depending on cutting yield, estimated rough value $1,500 - $3,000 USD
Certification Estimate
GIA or AGS once cut and polished; rough grading is less standardized
Investment Potential
Moderate, primarily valued as a specimen piece or speculative cutting rough
Similar Diamonds
Typical run-of-mine industrial or lower-gem quality rough diamond crystals
Setting Suggestions
Can be custom-set raw in an organic/rustic gold or platinum bezel setting
Care & Maintenance
Store separately to prevent scratching other jewelry; clean gently with warm soapy water
Interesting Facts
The triangular depressions on the surface are called trigons, formed by natural dissolution processes deep within the Earth
