Overall Assessment
An interesting, natural rough diamond specimen showing distinct growth lines and irregular crystallization. While its clarity and color grade are modest, its appeal lies in its raw, unaltered geological state, making it desirable for mineral collectors or custom jewelry designers.
Cut Quality
Not applicable (Uncut rough specimen)
Brilliance
Subdued due to rough, unpolished surface facets
Fire
Limited dispersion visible on raw surfaces
Scintillation
Minimal play of light until cut and polished
Proportions
Natural uncut proportions with irregular depth and girdle thickness
Symmetry
Natural asymmetrical crystal growth
Polish
Raw natural crystal faces with striations (trigons potentially present)
Fluorescence
Cannot be definitively determined without UV testing (Likely Faint to Medium Blue)
Inclusions
Internal cloudiness, feathers, and potential carbon spots or crystal inclusions typical of rough stones
Blemishes
Natural surface pitting, rough skin, and growth lines
Origin
Alluvial or primary kimberlite pipe deposit (African or Canadian origin typical)
Treatment Detection
No treatments detected; completely natural rough crystal
Estimated Value
$500 - $1,500 depending on cutting potential and purity
Certification Estimate
GIA or EGL rough certificate or gemological identification report
Investment Potential
Moderate collector value as a specimen, high risk as an investment unless precision cut yields a high-clarity stone
Similar Diamonds
Industrial or lower-gem-quality rough diamond specimens sold to collectors or custom lapidaries
Setting Suggestions
Organic bezel setting or wire-wrap to preserve its natural raw aesthetic as a pendant
Care & Maintenance
Store separately in a fabric-lined box to avoid scratching other jewelry, clean gently with warm soapy water and a soft brush
