Natural rough diamond crystal
Natural rough diamond crystal · Uncut raw crystal (elongated octahedron/irregular rough fragment)
Not applicable (uncut rough stone) Cut

Carat
Estimated 2.0 to 3.5 carats based on visual scale against fingers
Color
Near colorless to faint yellow (approx. J-K range)
Clarity
Included (approx. SI2 or I1 range due to internal graining and surface features)
Shape
Uncut raw crystal (elongated octahedron/irregular rough fragment)
Overall Assessment
This is an interesting, natural rough diamond crystal displaying raw geological characteristics. While not suitable for standard jewelry without cutting and polishing, it holds unique appeal as a raw mineral specimen.
Cut Quality
Not applicable (uncut rough stone)
Brilliance
Low to moderate due to rough, unpolished state and internal inclusions
Fire
Limited due to lack of standard facets and rough surface refraction
Scintillation
Minimal in current rough form
Proportions
Natural rough form, no standard table, depth, or angles applicable
Symmetry
Natural crystal symmetry, asymmetric due to breakage or uneven growth
Polish
Natural crystal faces (trigons and striations visible)
Fluorescence
Undetermined without UV testing
Inclusions
Internal graining, cloudiness, and feather-like fracture lines visible
Blemishes
Natural surface textures, growth lines, and possible surface etching
Origin
Alluvial or primary kimberlite rough origin (indeterminate exact mine without spectroscopy)
Treatment Detection
No obvious signs of artificial treatment; appears completely untreated and natural
Estimated Value
Nominal value as a rough specimen, highly dependent on cutting yield (rough market value approx $200 - $600 USD)
Certification Estimate
GIA or IGI would classify this as rough/unpolished diamond material
Investment Potential
Low as a polished gem investment, moderate as a unique collector's mineral specimen

Setting Suggestions
Can be custom-set in an organic, raw-style bezel setting using yellow or white gold to preserve its natural form
Care & Maintenance
Store separately to prevent scratching other materials; clean gently with warm soapy water and a soft brush
Interesting Facts
Displays natural crystal growth striations and curved surface features typical of rough diamond genesis deep within the Earth's mantle
