Natural rough crystal fragment
Natural rough crystal fragment · Uncut raw crystal (irregular fragment)
Not applicable (rough uncut crystal) Cut
Carat
Estimated 2.0 - 4.0 carats based on visual scale
Color
Light brown / yellowish-brown (near-colorless with strong warm body color)
Clarity
I2 - I3 (heavy internal fracturing, feather inclusions, and massive structural flaws)
Shape
Uncut raw crystal (irregular fragment)
Overall Assessment
An unpolished, heavily fractured natural rough diamond crystal fragment primarily suited for mineral collection, educational purposes, or industrial use rather than fine jewelry fabrication.
Cut Quality
Not applicable (rough uncut crystal)
Brilliance
Poor due to internal fracturing and lack of faceted optical design
Fire
Minimal dispersion visible only in small transparent window areas
Scintillation
Negligible due to opaque fracture networks and lack of facets
Proportions
Not applicable to raw rough material
Symmetry
Natural asymmetric crystal growth and cleavage patterns
Polish
Raw, unpolished natural crystal faces
Fluorescence
Indeterminate from visual assessment
Inclusions
Extensive internal fracturing, deep feathers, cleavage planes, and dark mineral inclusions
Blemishes
Natural growth striations, rough surface texture, chips, and broken cleavage faces
Origin
Alluvial or primary kimberlitic deposit origin
Treatment Detection
No evidence of artificial enhancement; entirely natural state
Estimated Value
Nominal value as a mineral specimen or industrial-grade diamond; limited gemological value due to severe fractures.
Certification Estimate
Gemological laboratories would classify this as industrial grade or specimen grade; major labs (GIA, IGI) would typically issue a rough report or identification note rather than a standard grading report.
Investment Potential
Low investment value for jewelry, primarily of interest to mineral collectors or industrial applications
Similar Diamonds
Other industrial or specimen-grade raw diamond crystals with high fracture density
Setting Suggestions
Wire-wrapped rough stone jewelry or organic raw mineral settings using protective yellow gold or sterling silver prongs
Care & Maintenance
Handle with extreme care; severe internal fracturing makes the crystal extremely fragile and susceptible to cleavage along structural planes upon impact
Interesting Facts
Raw diamond crystals often display natural triangular markings known as trigons on their octahedral faces, though this particular fragment shows dominant cleavage and fracture patterns.
