Overall Assessment
An interesting natural rough diamond crystal displaying characteristic growth lines and surface features, primarily suited for mineral collections or bespoke organic jewelry designs

Brilliance
Low due to uncut, rough nature and internal fractures
Fire
Limited dispersion visible on raw surfaces
Scintillation
Minimal due to absence of standard facets

Symmetry
Natural crystal symmetry showing typical octahedral growth planes
Polish
Raw natural crystal surfaces, unpolished
