Overall Assessment
An interesting and authentic natural rough diamond crystal displaying characteristic growth features, ideal for mineral collectors or custom organic jewelry design.
Cut Quality
Not applicable (Rough, un-cut stone)
Brilliance
Low (due to rough, unpolished surface)
Fire
Minimal dispersion in current rough state
Scintillation
Limited flash due to natural crystal faces rather than facets
Proportions
Natural uncut morphology, non-standard geometric proportions
Symmetry
Natural crystal symmetry showing octahedral growth lines
Polish
Natural rough crystal faces (trigons and growth striations visible)
Fluorescence
Unable to determine without UV testing (likely none to moderate)
Inclusions
Internal clouds, feather fractures, and dark mineral inclusions visible
Blemishes
Natural surface pitting, rough skin, and trigons

Estimated Value
Varies widely based on potential yield after cutting, roughly $300 - $800 in rough form
Certification Estimate
GIA or similar major lab if submitted for rough certification and tracking
Investment Potential
Moderate as a collector's mineral specimen, highly dependent on cutting yield if faceted
