Natural rough diamond crystal
Natural rough diamond crystal · Uncut octahedral or elongated rough crystal fragment
Not applicable (Rough, unpolished crystal) Cut
Carat
Estimated 1.50 to 2.50 carats based on visual scale
Color
Near-colorless to faint tint (approx. G-I range)
Clarity
Included (approx. I1 to I2 range due to visible internal fracturing and feathering)
Shape
Uncut octahedral or elongated rough crystal fragment
Overall Assessment
An interesting, natural rough diamond specimen exhibiting raw crystalline geometry, significant internal inclusions, and natural surface textures well-suited for specimen collectors or rustic organic jewelry.
Cut Quality
Not applicable (Rough, unpolished crystal)
Brilliance
Low due to lack of standard facet geometry and internal inclusions
Fire
Minimal dispersion observed in current rough state
Scintillation
Limited, reflecting light off natural cleavage planes and fracture surfaces rather than precision facets
Proportions
N/A for raw un-faceted crystal
Symmetry
Natural crystal symmetry, distorted growth habit
Polish
Natural crystal faces showing typical trigons and striations
Fluorescence
Indeterminate from visual assessment alone
Inclusions
Heavy internal feathering, cleavage planes, and cloud-like structures visible
Blemishes
Natural surface pitting, triangular growth marks (trigons), and irregular surface texture
Origin
Likely alluvial or primary kimberlitic deposit origin (Africa or Russia)
Treatment Detection
No signs of artificial treatment; completely natural state
Estimated Value
Valued primarily as an industrial specimen or raw collectible ($100 - $300 USD)
Certification Estimate
GIA or IGI would classify as Rough Gemstone / Natural Diamond Specimen
Investment Potential
Low investment liquidity; valued mainly for educational, mineral collection, or bespoke rustic jewelry purposes
Similar Diamonds
Other untreated raw diamond octahedrons and mineral crystal specimens
Setting Suggestions
Organic raw gemstone jewelry using bezel settings or wire-wrapping in yellow or white gold
Care & Maintenance
Handle with care to avoid propagating natural cleavage planes along internal fracture lines; clean gently with warm soapy water
