Overall Assessment
This is a fascinating specimen of an uncut natural rough diamond. While it contains significant internal inclusions and fractures, it possesses character and holds potential for a skilled lapidary to transform it into a unique custom-cut gemstone or preserve it as a raw collector's piece.
Cut Quality
Not Applicable (Uncut Rough)
Brilliance
Low due to lack of cut facets and internal inclusions
Fire
Minimal dispersion observed in current rough state
Scintillation
Limited, reflecting light off natural crystal faces rather than facets
Proportions
Not Applicable for rough diamond
Symmetry
Asymmetrical Natural Crystal Formation
Polish
Natural unpolished crystal faces and cleavage planes
Fluorescence
Undetermined without UV testing, likely Faint to Medium
Inclusions
Heavy central clouding, mineral crystals, dark carbon spots, and internal stress fractures
Blemishes
Natural surface trigons, growth lines, and rough cleavage/fracture marks
Origin
Natural alluvial or primary kimberlite deposit origin
Treatment Detection
No signs of artificial treatment; appears completely untreated and natural
Estimated Value
Varies widely based on potential yield after cutting, estimated rough value $1,000 - $3,000 USD
Certification Estimate
GIA or IGI would issue a rough diamond report or grade post-cut
Investment Potential
Moderate, highly dependent on the cutter's skill to maximize yield and clarity upon faceting
