Natural Rough Diamond
Natural Rough Diamond · Rough / Uncut (showing natural octahedral/dodecahredral features)
N/A (Rough crystal) Cut
Carat
Estimated 15-25 carats based on finger scale
Color
D-F (Colorless range)
Clarity
VS1 - VS2 (Estimated internal visibility)
Shape
Rough / Uncut (showing natural octahedral/dodecahredral features)
Overall Assessment
A substantial, high-quality rough diamond specimen with excellent color potential and high transparency.
Cut Quality
N/A (Rough crystal)
Brilliance
Low (Requires faceting to unlock brilliance)
Fire
Subtle dispersion visible at specific angles of the rough surface
Scintillation
Minimal in rough state
Proportions
Asymmetrical rough specimen
Symmetry
N/A (Natural crystal formation)
Polish
N/A (Natural surface textures/trigons)
Fluorescence
None visible in daylight
Inclusions
Few visible dark pinpoints and internal growth lines
Blemishes
Natural surface frosting and rhombohedral cleavage steps
Origin
Likely African (e.g., Botswana or South Africa)
Treatment Detection
None apparent; looks like a natural untreated crystal
Estimated Value
$40,000 - $85,000 (Highly variable based on yield and clarity)
Certification Estimate
GIA Rough Diamond Inspection (D Color, VS range)
Investment Potential
High, if the yield for a polished stone is predicted to be above 8-10 carats
Similar Diamonds
Comparable to large ethically sourced rough from De Beers sightholders
Setting Suggestions
Best suited for a custom 'rough-diamond' tension setting or kept as a specimen
Care & Maintenance
Protect from hard impacts; although 10 on Mohs scale, cleavage planes are vulnerable
Interesting Facts
The surface shows 'trigons' or growth marks characteristic of high-pressure formation deep in the mantle.
