Overall Assessment
A low-quality rough natural diamond specimen with significant structural inclusions and visible tint.
Cut Quality
N/A (Rough state)
Brilliance
Very Low (Restricted by rough surface and inclusions)
Fire
Very Low (Light cannot disperse through rough surface)
Scintillation
Negligible
Proportions
N/A (Natural crystal habit)
Symmetry
Poor (Natural uneven growth patterns)
Polish
N/A (Unpolished natural surface)
Fluorescence
Indeterminate from visual assessment
Inclusions
Large internal feathers, dark mineral crystals, and twinning wisps
Blemishes
Heavy trigons, surface reaching fractures, and skin irregularities
Origin
Likely African (e.g., DRC or Sierra Leone) based on morphology
Treatment Detection
None visible; appears to be raw, untreated mine-run material
Estimated Value
$400 - $1,200 (Highly dependent on yield and clarity after cutting)
Certification Estimate
GIA Rough Diamond Grading or Rough Diamond Analysis
Investment Potential
Low; high risk due to significant internal fractures and low color grade
Similar Diamonds
Conflict-free rough octahedrons or alluvial diamonds
Setting Suggestions
Tension setting for raw crystals or custom claw setting for 'raw' jewelry
Care & Maintenance
Avoid ultrasonic cleaners due to fractures; clean with warm soapy water
Interesting Facts
The triangular surface markings are called 'trigons,' a hallmark of natural diamond growth
