Rough natural diamond specimen (or industrial carbonado/bort)
Rough natural diamond specimen (or industrial carbonado/bort) · Uncut, irregular rough crystal formation
Not applicable (uncut rough crystal) Cut
Carat
Estimated between 5.0 to 15.0 carats based on visible bulk dimensions
Color
Dark gray to opaque black (industrial grade color)
Clarity
I3 / Included / Opaque due to heavy internal fractures and inclusions
Shape
Uncut, irregular rough crystal formation
Overall Assessment
This image depicts a raw, uncut natural diamond or industrial-grade carbonaceous rough specimen showing characteristic natural surface textures, pitting, and irregular form rather than a faceted gemstone
Cut Quality
Not applicable (uncut rough crystal)
Brilliance
Minimal to none due to opaque nature and lack of facet structure
Fire
Absent due to opacity and lack of cut dispersion
Scintillation
None in current rough state
Proportions
N/A for raw rough stones
Symmetry
Asymmetrical raw crystal form
Polish
Raw, natural unpolished crystal faces with typical trigons and etching marks
Fluorescence
Cannot be reliably determined without UV testing, likely inert
Inclusions
Heavy clouding, graphite spots, micro-fractures, and mineral inclusions typical of raw diamond
Blemishes
Natural surface pitting, resorption cavities, and growth marks
Origin
Likely alluvial or primary kimberlite deposit origin (African, Russian, or South American source)
Treatment Detection
No signs of enhancement; purely natural rough specimen
Estimated Value
Nominal industrial value or collector specimen value ranging from $50 to $300 depending on exact weight and purity
Certification Estimate
Industrial evaluation or basic gemological certificate (GIA or EGL) confirming natural rough status
Investment Potential
Low investment potential for jewelry use; strictly valued as a mineral specimen or for industrial abrasive use
Similar Diamonds

Setting Suggestions
Wire-wrapped rough stone pendant or custom organic bezel setting to preserve raw aesthetic
Care & Maintenance
Store securely to prevent chipping along cleavage planes; clean gently with warm soapy water and soft brush
Interesting Facts
Rough diamonds showcase the natural octahedral or irregular crystal growth of carbon formed deep within the Earth's mantle under extreme pressure
