Natural (Rough Crystal / Industrial or Specimen Grade)
Natural (Rough Crystal / Industrial or Specimen Grade) · Rough Uncut Octahedral/Irregular Fragment
Not applicable (Rough uncut specimen) Cut
Carat
Estimated 2.0 - 3.5 carats
Color
Off-white to light yellow / brown tinged skin (natural rough cortex)
Clarity
I2 - I3 (Heavily included with internal fractures, feathering, and inclusions)
Shape
Rough Uncut Octahedral/Irregular Fragment
Overall Assessment
This is a raw, natural diamond crystal fragment showcasing heavy internal fracturing and natural surface characteristics, better suited for a mineral collection than faceted jewelry use.
Cut Quality
Not applicable (Rough uncut specimen)
Brilliance
Low to moderate due to heavy internal fracturing and lack of standard facet alignment
Fire
Minimal, obstructed by internal fracture planes and rough surfaces
Scintillation
Poor, limited to flash effects from internal cleavage planes
Proportions
N/A for rough stones; exhibits natural crystal elongation
Symmetry
Natural asymmetrical rough crystal form
Polish
Unpolished natural crystal faces with some etched features and rough fracture planes
Fluorescence
Cannot be definitively determined without UV testing, likely inert to faint
Inclusions
Extensive internal fracturing, feathering, potential mineral inclusions (graphite or sulfides)
Blemishes
Natural surface trigons, rough skin, pitting, and possible thermal or mechanical fracture marks
Origin
Alluvial or primary kimberlite deposit (African, Canadian, or Russian rough origin typical for such specimens)
Treatment Detection
None detected; appears entirely natural and untreated as-mined rough
Estimated Value
Nominal specimen or industrial value ($50 - $200 USD depending on exact weight and fluorescence)
Certification Estimate
Not certified; would likely receive a rough diamond report or identification certificate from GIA noting heavy natural characteristics
Investment Potential
Low investment potential for jewelry resale; strictly collectible mineral specimen value
Similar Diamonds
Other industrial-grade or raw mineral specimen rough diamonds
Setting Suggestions
Wire-wrapped pendant, organic rustic bezel setting, or kept as a raw mineral specimen
Care & Maintenance
Handle with care to prevent further propagation of natural internal fractures; avoid harsh ultrasonic cleaners
Interesting Facts
Displays the natural vitreous to adamantine luster typical of uncut diamond rough, showing natural growth marks and striations
