Rough natural diamond crystal or heavily weathered matrix mineral
Rough natural diamond crystal or heavily weathered matrix mineral · Uncut raw crystal / Irregular rough formation
Not Applicable (Uncut Rough) Cut
Carat
Estimated 2.50 to 4.00 carats based on visual mass
Color
Dark/opaque with translucent areas
Clarity
Included / Industrial Grade
Shape
Uncut raw crystal / Irregular rough formation
Overall Assessment
This appears to be an unpolished, rough mineral or low-grade industrial diamond crystal showing natural growth features rather than a faceted gem.
Cut Quality
Not Applicable (Uncut Rough)
Brilliance
Low due to lack of standard facet geometry and opaque nature
Fire
Minimal to none due to rough surface structure
Scintillation
Poor, lacks facet-based light return
Proportions
N/A for raw un cut mineral formations
Symmetry
Natural asymmetric crystal growth
Polish
Raw, unpolished surface with natural growth lines and striations
Fluorescence
Unable to determine without UV testing
Inclusions
Heavy internal clouding, feather fractures, and dark carbon spots
Blemishes
Natural surface trigons, etching channels, and abrasion marks
Origin
Alluvial or primary kimberlite pipe deposit
Treatment Detection
No treatments detected; completely natural raw state
Estimated Value
$100 - $300 for specimen or industrial use
Certification Estimate
Industrial evaluation or specialized rough sorting (De Beers/rough dealers)
Investment Potential
Low investment value; primarily of interest as a mineral specimen
Similar Diamonds
Industrial-grade boart or low-quality raw octahedral diamond crystals
Setting Suggestions
Wire-wrapped or organic prong setting to showcase raw mineral aesthetic
Care & Maintenance
Avoid harsh impacts which could exploit natural cleavage planes
