Carat
Estimated approximately 1.50 to 2.50 carats based on visual scale
Color
Near-colorless to light brown/grey tint

I1 to I3 (Included rough with notable internal features)
Shape
Rough elongated crystal (octahedral/dodecahedral habit altered by natural growth)
Overall Assessment
An interesting, natural rough diamond crystal specimen showing characteristic growth features, ideal for mineral collectors or custom organic-style jewelry rather than traditional faceted diamond markets.
Cut Quality
Not applicable (Rough crystal, uncut and unpolished)
Brilliance
Low due to rough and untreated surface condition
Fire
Minimal due to unpolished crystal faces restricting light dispersion
Scintillation
Limited, reflecting light off raw crystal faces rather than faceted surfaces
Proportions
Natural elongation with irregular depth and growth lines
Symmetry
Natural asymmetrical rough formation
Polish
Natural crystal faces (trigons and striations visible)
Fluorescence
Unknown (requires UV testing)
Inclusions
Internal clouds, feather fractures, and internal graining visible
Blemishes
Natural surface etch channels, trigons, and surface irregularities
Origin
Alluvial or primary kimberlite deposit origin
Treatment Detection
No signs of artificial treatment; completely natural rough specimen
Estimated Value
Varies widely based on industrial vs. gem-quality potential, roughly $100 to $500 as a mineral specimen
Certification Estimate
GIA or HRD as rough diamond analysis, though typically graded after cutting
Investment Potential
Collector mineral value rather than standard diamond investment grade

Setting Suggestions
Raw crystal bezel setting in yellow gold or sterling silver for organic jewelry
