Natural Diamond (Rough / Uncut Specimen)
Natural Diamond (Rough / Uncut Specimen) · Rough Crystal / Natural Octahedral Fragment
Not applicable (Rough uncut stone) Cut
Carat
Estimated 3.50 - 5.00 carats based on visual scale
Color
Estimated Near Colorless (G-J range)
Clarity
Estimated Included (I1-I2) due to internal stress patterns and feather features
Shape
Rough Crystal / Natural Octahedral Fragment
Overall Assessment
An intriguing natural rough diamond specimen exhibiting characteristic growth features, striations, and internal stress lines, offering potential for custom lapidary cutting or as a raw collector mineral.
Cut Quality
Not applicable (Rough uncut stone)
Brilliance
Low (typical of uncut rough stone prior to faceting)
Fire
Limited light dispersion due to rough surface and internal inclusions
Scintillation
Minimal sparkle; reflects light diffusely off natural crystal faces
Proportions
Natural rough morphology, unproportioned
Symmetry
Natural crystal growth symmetry (distorted octahedron)
Polish
Natural crystal faces (trigons and striations visible)
Fluorescence
Unable to determine without UV testing (likely Faint to Medium)
Inclusions
Prominent internal feather fractures, graining lines, and potential cloud formations
Blemishes
Natural surface etch channels, growth lines, and trigons
Origin
Likely alluvial or primary kimberlite pipe origin (African or Canadian source)
Treatment Detection
No evidence of artificial treatment; appears completely untreated natural rough
Estimated Value
Varies widely based on potential cut yield (rough industrial to mid-tier jewelry grade)
Certification Estimate
GIA or HRD for rough origin reporting and characterization
Investment Potential
Moderate, primarily valued as a specimen or for custom cutting potential
