Not applicable (Uncut rough stone) Cut
Carat
Estimated 0.85 to 1.25 carats
Color
Light brown / off-white tint (K-M range equivalent)
Clarity
Included (I1-I2 equivalent due to natural surface features and internal inclusions)
Shape
Uncut octahedral or irregular crystal fragment (Rough)
Overall Assessment
An interesting, genuine natural rough diamond crystal displaying characteristic surface growth features and crystal habits, highly suitable for organic, uncut jewelry designs or custom cutting.
Cut Quality
Not applicable (Uncut rough stone)
Brilliance
Low to moderate due to rough, unpolished surfaces scattering light externally
Fire
Minimal due to lack of precision-cut facets
Scintillation
Limited, reflecting light off natural crystal faces rather than internal facet mirrors
Proportions
Natural rough morphology, no standard faceted proportions
Symmetry
Natural crystalline symmetry (distorted octahedral/dodecahedral habits)
Polish
Natural crystal faces (trigons and striations visible)
Fluorescence
Indeterminate from visual assessment (Typically inert to moderate blue in rough)
Inclusions
Natural mineral inclusions, clouds, and feather fractures typical of rough diamonds
Blemishes
Natural surface pitting, trigons, and etching marks
Origin
Natural subterranean origin (likely alluvial or primary kimberlitic deposit)
Treatment Detection
No treatments detected; completely untreated natural rough
Estimated Value
$300 - $800 depending on cutting yield and final polished outcome
Certification Estimate
GIA or specialized rough grading services (e.g., De Beers rough categorization)
Investment Potential
Niche market; value depends heavily on whether it is cut and polished into a finished gem
