Natural diamond crystal or heavy inclusion-laden rough
Natural diamond crystal or heavy inclusion-laden rough · Rough uncut crystal / Irregular block
Uncut / Raw crystal (Not applicable) Cut
Carat
Estimated 3.50 - 5.00 carats based on visual scale and density
Color
J-K range with brownish-gray undertones
Clarity
I3 (Heavy inclusions, heavily fractured and included)
Shape
Rough uncut crystal / Irregular block
Overall Assessment
A fascinating raw diamond specimen with heavy structural inclusions, better suited for mineral collections or raw-stone jewelry rather than traditional faceted applications
Cut Quality
Uncut / Raw crystal (Not applicable)
Brilliance
Low due to dense internal inclusions and fractures
Fire
Minimal spectral dispersion visible mostly at raw fracture edges
Scintillation
Poor due to lack of facet organization
Proportions
Uncut specimen, standard pavilion/table angles not applicable
Symmetry
Asymmetrical raw crystal form
Polish
Natural rough surface textures
Fluorescence
Inert to Faint Blue under UV
Inclusions
Massive internal feathering, cloud formations, dark carbon spots, and internal stress fractures
Blemishes
Natural surface roughness, trigon growth marks, and minor chipping
Origin
Likely alluvial or primary kimberlite pipe deposit (African or Canadian origin)
Treatment Detection
No treatments detected; completely untreated natural state
Estimated Value
$500 - $1,500 depending on industrial vs. low-grade gem potential
Certification Estimate
GIA or IGI (Rough diamond grading report or Industrial/Near-gem classification)
Investment Potential
Low investment value for jewelry, primarily of interest to mineral collectors or industrial applications
Similar Diamonds
Industrial-grade or raw collector's rough diamonds of comparable weight
Setting Suggestions
Wire-wrapped raw stone pendant or bespoke organic bezel setting in yellow or rose gold
Care & Maintenance
Handle with care due to internal fracture lines; avoid ultrasonic cleaners which could worsen internal cracking
Interesting Facts
Raw diamond crystals retain their natural geological history, showing crystal growth steps and natural etching marks untouched by human cutters
