Overall Assessment
This is a fascinating specimen of a natural, uncut rough diamond displaying raw crystal characteristics, growth lines, and natural morphology prior to any lapidary processing.
Cut Quality
Not applicable (Rough, uncut stone)
Brilliance
Limited brilliance due to rough, unpolished surface and lack of optical facets
Fire
Minimal dispersion visible through raw crystal faces
Scintillation
Low scintillation due to absence of standard pavilion and crown facets
Proportions
Natural asymmetrical rough proportions, unpolished
Symmetry
Natural crystal symmetry (distorted octahedral/dodecahedral growth)
Polish
Natural crystal faces (trigons and striations visible)
Fluorescence
Cannot be determined without UV testing (Likely Faint to Medium Blue)
Inclusions
Internal feather fractures, clouds, and potential mineral crystal inclusions typical of rough stones
Blemishes
Natural surface pitting, trigons (growth triangles), and striations on crystal faces
Origin
Likely alluvial or primary kimberlite pipe origin (African or Canadian source)
Treatment Detection
No signs of artificial treatment; completely natural untreated rough
Estimated Value
$1,500 - $3,500 depending on final cut yield and internal cleavage planes
Certification Estimate
GIA (Gemological Institute of America) Rough Diamond Report
Investment Potential
Moderate potential as a collector piece or custom-cut investment, dependent on recovery yield
Similar Diamonds
Comparable natural rough melee and medium-size uncut diamond crystals sold to bespoke cutters
Setting Suggestions
Organic bezel setting or raw crystal wire-wrap to preserve the natural aesthetic
Care & Maintenance
Store separately to prevent scratching other jewelry; clean gently with warm soapy water and a soft brush
Interesting Facts
Rough diamonds display natural growth marks called trigons, which are microscopic triangular etchings formed deep within the Earth's mantle
