Estimated D-E (Excellent Colorless Range)
Clarity
Estimated VS1-VS2 (subject to cutting loss and internal strain)
Shape

Overall Assessment
A high-quality, high-transparancy rough diamond specimen with significant potential for a high-grade faceted stone.
Cut Quality
N/A (Rough/Uncut)
Brilliance
N/A (Requires faceting to achieve refractive brilliance)
Fire
N/A (Light scattering limited in rough state)
Scintillation
N/A (Patterning absent in uncut state)
Proportions
N/A (Raw specimen)
Symmetry
N/A (Natural uneven growth)
Polish
N/A (Natural adamantine luster)
Fluorescence
None visible under standard lighting
Inclusions
Few visible internal feathers and slight surface trigons on growth faces
Blemishes
Natural percussion marks and conchoidal fractures common in rough specimens
Origin
Likely African or Canadian (consistent with high-purity alluvial rough)
Treatment Detection
None detected; appears to be raw untreated rough
Estimated Value
$3,000 - $7,000 (Highly dependent on yield and final clarity)
Certification Estimate
GIA Rough Diamond Evaluation Report (estimated D Color)
Investment Potential
High (value significantly increases post-cut if it yields a 1ct+ Colorless stone)

Setting Suggestions
Custom 'Rough Diamond' prong setting or tension setting for organic look; ideally faceted first
Care & Maintenance
Avoid sharp impacts as rough diamonds have directional cleavage planes despite their hardness
Interesting Facts
The flat surfaces show internal stress patterns and light refraction typical of pure carbon cubic structures
