Overall Assessment
This is a fascinating specimen of a natural, uncut rough diamond crystal showing raw geological characteristics, ideal for mineral collectors or custom organic jewelry rather than standard investment gemstone cutting.
Cut Quality
Not Applicable (Rough, Uncut Specimen)
Brilliance
Low (due to rough surface and natural crystal opacity)
Fire
Minimal dispersion in raw state
Scintillation
Poor due to lack of standard facet angles
Proportions
Natural rough morphology, no standard pavilion or table percentages
Symmetry
Natural crystal symmetry, distorted octahedral growth
Polish
Natural crystal faces (trigons and striations visible)
Fluorescence
Cannot be determined visually without UV testing
Inclusions
Internal feather fractures, carbon spots, cloud clusters
Blemishes
Natural surface etching, trigons, and surface pitting
Origin
Alluvial or primary kimberlite pipe deposit (African or Canadian origin likely)
Treatment Detection
No treatments detected; entirely natural rough specimen
Estimated Value
Speculative rough diamond market value, approximately $100 - $300 depending on cutting potential
Certification Estimate
GIA or similar major lab if polished, but typically graded as rough parcel by weight
Investment Potential
Low as raw specimen for resale, moderate as collector piece or custom jewelry piece
