Overall Assessment
An interesting natural rough diamond crystal featuring visible growth textures and a prominent inclusion, best appreciated in its raw geological state.
Cut Quality
Not applicable (Rough uncut crystal)
Brilliance
Low due to lack of standard facet angles and rough surface
Fire
Minimal dispersion visible through raw curved surfaces
Scintillation
Limited, reflecting light from natural crystal faces rather than facets
Proportions
Natural rough proportions, deep crystal body
Symmetry
Natural asymmetric crystal growth form
Polish
Natural unpolished crystal faces with typical trigons/striations
Fluorescence
Cannot be determined without UV testing (likely none to faint)
Inclusions
Large central inclusion, possibly a crystal inclusion or dissolution cavity
Blemishes
Natural surface etching marks, growth lines, and striations on crystal faces
Origin
Likely alluvial or primary kimberlite deposit origin
Treatment Detection
No signs of artificial treatment; completely natural rough specimen
Estimated Value
Varies widely based on industrial vs. gem-quality potential, roughly $500 - $2,000 as a specimen
Certification Estimate
GIA or similar lab for rough weight and origin report
Investment Potential
Collected more as a mineral specimen or curiosity than a standard financial asset

Setting Suggestions
Raw mineral specimen pendant or organic wire-wrapped custom mounting
Care & Maintenance
Store separately to avoid scratching other gems; clean gently with warm soapy water
