Natural diamond (rough crystal fragment / industrial grade)
Natural diamond (rough crystal fragment / industrial grade) · Uncut rough / irregular crystal fragment
Uncut / Unpolished (Not applicable) Cut
Carat
Estimated 2.0 to 3.5 carats
Color
Near-colorless to light brown/grey tint (J-L range)
Clarity
I3 (heavy inclusions, fractures, and surface irregularities)
Shape
Uncut rough / irregular crystal fragment
Overall Assessment
This specimen is a raw, untreated natural diamond crystal fragment of industrial or low specimen quality, displaying characteristic natural growth strictions and significant internal fracturing.
Cut Quality
Uncut / Unpolished (Not applicable)
Brilliance
Poor to fair due to heavy fracturing and lack of facet alignment
Fire
Limited spectral dispersion visible primarily along fractured internal planes
Scintillation
Minimal sparkle due to raw, unfaceted surface texture
Proportions
Uncut crystal specimen; standard proportions do not apply
Symmetry
Natural crystal symmetry (distorted, irregular growth)
Polish
Raw natural crystal surface with parallel strictions and growth lines
Fluorescence
Cannot be determined without UV testing (likely none to faint)
Inclusions
Extensive internal fractures, feather inclusions, internal cloudiness, and mineral trapped specs
Blemishes
Natural surface etching, rough growth lines, chips, and cavities
Origin
Alluvial or primary kimberlite deposit (undetermined specific geographic origin)
Treatment Detection
No signs of artificial enhancement (untreated natural rough state)
Estimated Value
Nominal value as a rough mineral specimen or industrial material (under $100 USD)
Certification Estimate
Not commercially certifiable for jewelry; typically sold as industrial or specimen grade without major lab certificates (GIA/AGS/IGI)
Investment Potential
None as an investment gem; purely of educational or mineral specimen interest
Similar Diamonds
Industrial-grade boart or low-quality alluvial rough diamond fragments
Setting Suggestions
Wire-wrapped rough stone jewelry or organic bezel settings if used as a raw mineral pendant
Care & Maintenance
Store separately to prevent scratching other materials; avoid harsh chemical cleaners and ultrasonic baths due to structural internal fractures
Interesting Facts
Most mined diamonds (roughly 80%) are of industrial quality rather than gem quality, used for cutting, grinding, and drilling tools rather than jewelry
