Natural rough diamond / mineral specimen showing complex internal crystal growth structures
Natural rough diamond / mineral specimen showing complex internal crystal growth structures · Rough crystal / Uncut natural form with irregular elongated morphology
Not Applicable (Uncut rough specimen) Cut

Carat
Estimated 3.50 to 5.00 carats based on visual scale and density
Color
Brownish-grey / Fancy Natural Brown tint
Clarity
Included / I3 due to prominent ladder-like internal growth patterns, feather fractures, and heavy inclusions
Shape
Rough crystal / Uncut natural form with irregular elongated morphology
Overall Assessment
This is a captivating natural rough diamond specimen exhibiting unusual internal growth features rather than a traditional faceted gem. Its value lies in its geological curiosity and raw mineral beauty rather than optical brilliance
Cut Quality
Not Applicable (Uncut rough specimen)
Brilliance
Low to moderate due to uncut nature and heavy internal opacity
Fire
Minimal dispersion observed in rough state
Scintillation
Limited flash due to lack of faceted geometry
Proportions
Natural rough dimensions, non-standardized proportions
Symmetry
Natural asymmetrical crystal growth formation
Polish
Natural crystal faces (octahedral growth lines and striations visible)
Fluorescence
Likely Inert to Medium Blue under UV (typical for many natural rough crystals)
Inclusions
Pronounced ladder-like internal planes, tension fractures, and clouded regions
Blemishes
Natural surface trigons, etching channels, and rough skin textures
Origin
Natural alluvial or primary kimberlitic deposit origin
Treatment Detection
No signs of artificial treatment; completely untreated natural state
Estimated Value
Minimal gem-grade value as cut stone; valued primarily as a mineral specimen or for industrial use, roughly $100 - $300
Certification Estimate
GIA or similar major laboratory report for rough origin and identity confirmation
Investment Potential
Low investment potential for jewelry resale, but of moderate interest to mineral collectors
Similar Diamonds
Other industrial-grade or specimen-grade rough diamond crystals with heavy internal lattice patterns
Setting Suggestions
Wire-wrapped pendant, bespoke raw crystal bezel setting, or unmounted mineral display
Care & Maintenance
Avoid harsh impacts, ultrasonic cleaners, and thermal shock due to internal tension fractures
Interesting Facts
The ladder-like internal structure visible is a fascinating example of anomalous crystal growth and natural stress within the diamond lattice during formation deep in the Earth's mantle
