Natural Diamond (Rough Crystal or Raw Fragment)
Natural Diamond (Rough Crystal or Raw Fragment) · Rough / Uncut Octahedral / Irregular Crystal Fragment
Not applicable (uncut raw crystal form) Cut
Carat
Approximately 1.5 - 2.5 carats based on visual scale against fingers
Color
Near-colorless to light brown/grey tint (estimated G-I range)
Clarity
Included (I1 - I3) due to visible surface fractures, cleavage planes, and inclusions
Shape
Rough / Uncut Octahedral / Irregular Crystal Fragment
Overall Assessment
An interesting, natural raw diamond crystal fragment displaying characteristic growth features and cleavage planes, ideal for bespoke organic jewelry rather than traditional faceted settings.
Cut Quality
Not applicable (uncut raw crystal form)
Brilliance
Low to moderate due to rough surfaces and internal fractures obscuring light return
Fire
Minimal dispersion visible on raw crystal faces
Scintillation
Poor sparkle until cut and polished due to lack of standard facet geometry
Proportions
N/A for raw crystals, shows natural growth habit
Symmetry
Natural crystalline symmetry (distorted octahedral/cubic form with cleavage steps)
Polish
Natural crystal faces (trigons and rough growth lines visible)
Fluorescence
Indeterminate from visual assessment alone, likely None to Faint
Inclusions
Internal feather fractures, carbon spots, and cleavage planes visible
Blemishes
Natural rough surface graining, pitting, and fractured edges
Origin
Likely alluvial or primary kimberlite pipe deposit (Africa, Canada, or Russia)
Treatment Detection
No evidence of artificial treatments; appears entirely untreated and natural
Estimated Value
Modest value as a raw specimen or industrial/low-grade jewelry stone, roughly $300 - $800 depending on cutting yield
Certification Estimate
GIA or IGI (would be evaluated as a rough diamond parcel or raw specimen)
Investment Potential
Low as a polished gem investment, but unique appeal for bespoke rough-stone jewelry collectors

Setting Suggestions
Raw diamond jewelry style using a bezel or wire-wrap setting in yellow or white gold to preserve its organic form
Care & Maintenance
Avoid harsh impacts due to natural cleavage planes which make it susceptible to splitting along crystal lines
Interesting Facts
Natural rough diamonds retain the exact geometric shape they formed in deep within the Earth over billions of years
