Natural rough diamond crystal
Natural rough diamond crystal · Uncut raw crystal (Irregular / Dodecahedral form)
Not applicable (Rough, unpolished crystal) Cut
Carat
Estimated 3 to 5 carats based on visual proportion
Color
Estimated near-colorless to light yellow tint (G-J range)
Clarity
I3 (Heavy visible inclusions, feather fractures, and dark carbon spots)
Shape
Uncut raw crystal (Irregular / Dodecahedral form)
Overall Assessment
This is a fascinating specimen of a natural rough diamond featuring prominent internal carbon inclusions and natural fracture lines, highly educational but lacking gem-quality clarity for traditional cutting
Cut Quality
Not applicable (Rough, unpolished crystal)
Brilliance
Low to moderate due to heavy internal fractures and lack of faceting
Fire
Minimal dispersion observed in its rough, unpolished state
Scintillation
Poor, lacking standard faceted return of light
Proportions
Natural rough form; no standardized table, depth, crown, or pavilion angles
Symmetry
Natural crystal symmetry, distorted growth patterns
Polish
Raw crystal surface with natural growth lines (trigons/striations)
Fluorescence
Cannot be definitively determined without UV testing, likely None to Faint
Inclusions
Prominent dark carbon inclusion in the center, extensive internal feather fractures, and cloud formations
Blemishes
Natural surface etch channels, pits, and rough unpolished faces
Origin
Alluvial or primary kimberlitic pipe deposit (African, Russian, or Canadian origin)
Treatment Detection
No treatments detected; completely untreated natural rough stone
Estimated Value
Industrial to low specimen grade, estimated between $100 to $500 depending on weight and structural integrity
Certification Estimate
GIA would likely issue a Diamond Dossier or Identification Report noting rough status
Investment Potential
Low investment potential for resale, primarily valued as a mineral specimen or educational piece
Similar Diamonds

Setting Suggestions
Best suited for organic raw crystal jewelry, wire-wrapping, or decorative mineral collections
Care & Maintenance
Handle with care to prevent breakage along natural cleavage planes; clean gently with warm soapy water and a soft brush
Interesting Facts
Rough diamonds showcase the natural crystal habits in which carbon crystallizes deep within the Earth's mantle before being brought to the surface by volcanic activity
