Overall Assessment
A fascinating, raw, and organically shaped diamond specimen featuring primitive faceting and a prominent dark inclusion, holding more value as a unique natural curiosity than a traditional gemstone
Cut Quality
Poor (Untraditional artisanal or primitive bead cut)
Brilliance
Low due to heavy inclusions and primitive facet layout
Fire
Minimal due to cloudy clarity and rough faceting
Scintillation
Poor, limited flash due to internal dispersion barriers
Proportions
Non-standard, highly variable proportions due to natural crystal habit
Symmetry
Poor / Asymmetrical

Unknown without UV testing (likely medium blue if natural)
Inclusions
Heavy internal clouding, feathers, and a distinct dark carbon spot near the apex

Estimated Value
Low commercial value, highly dependent on collector market for uncut crystals
