Natural rough diamond crystal
Natural rough diamond crystal · Uncut raw crystal (elongated, irregular octahedral/dodecahedral fragment)
Not applicable for rough stones (Uncut natural state) Cut
Carat
Estimated approximately 1.5 to 2.5 carats based on visual scale against fingers
Color
Near-colorless to light brown tint (Estimated G-J range)
Clarity
Included (Rough stone containing internal fractures, inclusions, and natural crystal features; estimated SI2-I1 if cut)
Shape
Uncut raw crystal (elongated, irregular octahedral/dodecahedral fragment)
Overall Assessment
An interesting and genuine natural rough diamond crystal displaying characteristic surface features and internal inclusions, holding potential for either collector display or professional cutting into a finished gemstone
Cut Quality
Not applicable for rough stones (Uncut natural state)
Brilliance
Limited due to rough surface and uncut state
Fire
Minimal in raw state; requires proper faceting to exhibit dispersion
Scintillation
Low in unpolished, rough form
Proportions
Not applicable for rough uncut stones
Symmetry
Natural crystal symmetry, asymmetric due to being a raw crystal fragment and potential breakage
Polish
Natural crystal faces (trigons and growth lines visible)
Fluorescence
Unknown (requires UV testing)
Inclusions
Visible internal feather fractures, dark carbon spots, and crystal inclusions typical of rough diamonds
Blemishes
Natural surface textures, pitting, and irregular cleavage planes
Origin
Natural origin, likely from alluvial or primary kimberlite deposits (Africa, Canada, or Russia)
Treatment Detection
No treatments detected; appears completely untreated in its raw state
Estimated Value
Varies widely based on weight retention upon cutting, typically valued as industrial or lower-tier gem-quality rough ($200 - $800 depending on exact weight and cutting potential)
Certification Estimate
GIA or similar major gemological lab would issue a Rough Diamond Description Report or Kimberley Process certificate
Investment Potential
Moderate; value is speculative until cut, polished, and officially certified
Similar Diamonds
Other alluvial or mine-run rough diamond crystals of comparable size and clarity
Setting Suggestions
Best showcased in a bespoke raw diamond or organic-style wire-wrap setting, or destined for professional cutting and polishing
Care & Maintenance
Store separately to prevent scratching other gemstones; clean with mild soapy water and a soft brush
Interesting Facts
Rough diamonds retain their unaltered geological history, often preserving natural growth markings like trigons on their crystal faces
