Overall Assessment
An interesting, natural rough diamond crystal displaying characteristic surface textures and internal flaws, best suited for bespoke rough-stone jewelry or as a mineral specimen
Cut Quality
Not Applicable (Uncut Rough)
Brilliance
Low due to unpolished and rough nature
Fire
Minimal due to lack of faceted geometry
Scintillation
Low, limited to reflections off natural crystal planes
Proportions
Not Applicable for rough stones
Symmetry
Natural crystalline symmetry showing irregular growth patterns
Polish
Natural crystal faces (trigons and striations present)
Fluorescence
Cannot be determined without UV testing (Likely Faint to Medium Blue if natural)
Inclusions
Heavy internal feather fractures, dark pinpoints, and clouds visible
Blemishes
Natural surface etch channels, pits, and rough skin textures
Origin
Likely alluvial or primary pipe deposit (African, Canadian, or Russian origin)
Treatment Detection
No signs of artificial treatments; completely natural rough state
Estimated Value
Varies significantly based on cutting potential, roughly $500 - $1,500 USD
Certification Estimate
GIA or similar major lab (Rough stone reporting weight and origin)
Investment Potential
Moderate as a collector specimen, but low as a cut investment stone due to inclusions
Similar Diamonds
Other industrial or low-gem-quality rough diamond crystals of similar size
Setting Suggestions
Raw uncut diamond jewelry using bezel or wire-wrap settings in yellow or white gold
Care & Maintenance
Clean with mild soapy water and a soft brush; avoid harsh ultrasonic cleaners due to internal feather inclusions
Interesting Facts
Rough diamonds preserve the geological history of the Earth's mantle and often display natural triangular growth marks called trigons
