Overall Assessment
An interesting, natural rough diamond crystal in its un-faceted state, possessing characteristic growth features and a translucent appearance suitable for custom organic jewelry or a mineral collection.
Cut Quality
Not applicable (Rough, un-faceted specimen)
Brilliance
Low due to lack of facets and translucent/milky nature
Fire
Minimal dispersion due to uncut rough state
Scintillation
Absent due to lack of standard faceting
Proportions
Natural growth form, roughly spherical/dodecahedral habit
Symmetry
Natural crystal symmetry showing curved faces and striations
Polish
Natural unpolished crystal skin (trigons and surface texture visible)
Fluorescence
Cannot be determined without UV testing
Inclusions
Cloudy internal structures, feather fractures, and micro-inclusions
Blemishes
Natural surface pitting, etch channels, and growth marks
Origin
Likely alluvial or primary kimberlite pipe deposit (African or Canadian origin)
Treatment Detection
No treatments detected, completely natural rough stone
Estimated Value
Varies widely based on industrial vs. gem-quality cutting potential, roughly $300 - $800
Certification Estimate
GIA or similar major lab for rough diamond origin verification
Investment Potential
Collectible rough stones hold steady value, but lower than top-tier faceted diamonds
Similar Diamonds
Other natural un-cut gem-grade diamond crystals of similar size
Setting Suggestions
Raw diamond pendant or organic bezel setting to preserve natural crystal form
Care & Maintenance
Store separately to avoid scratching other jewelry, clean with warm soapy water and a soft brush
Interesting Facts
Rough diamonds often exhibit curved faces and triangular growth marks called trigons on their surfaces
