Rough crystal / Irregular octahedral or distorted crystal form
Overall Assessment
An interesting and genuine natural rough diamond crystal displaying classic geological features such as rounded edges and surface texture, ideal for mineral collectors or custom organic jewelry design.
Cut Quality
Not applicable (Rough, unpolished crystal)
Brilliance
Limited to surface luster of rough faces; low until faceted and polished
Fire
Minimal dispersion in current rough state
Scintillation
Low to none in current unpolished state
Proportions
Natural rough proportions, heavily dependent on future cutting orientation
Symmetry
Natural crystal symmetry (distorted octahedral/rounded edges)
Polish
Unpolished natural crystal faces, displaying characteristic triangular growth markings (trigons)
Fluorescence
Unknown / Untested
Inclusions
Internal crystal inclusions, feathers, and potential pinpoint inclusions visible under magnification
Blemishes
Natural surface textures, pitting, resorption cavities, and growth lines
Origin
Alluvial deposit or primary kimberlite pipe origin (Africa, Canada, or Australia)
Treatment Detection
None detected; completely untreated natural rough diamond
Estimated Value
Varies widely depending on weight and cut yield, roughly $500 - $2,000 USD as a collector mineral specimen or potential cut stone
Certification Estimate
GIA or AGS origin report if submitted as rough diamond
