Overall Assessment
A classic example of a natural, raw diamond crystal showing visible octahedral formation and natural growth characteristics.
Cut Quality
Uncut / Raw (Not graded for cut)
Brilliance
Low (Diffusion through natural surface texture)
Fire
Minimal in raw state
Scintillation
Low (Rough surface disrupts light return)
Proportions
Standard octahedral growth structure; trigons visible on faces
Symmetry
Poor (Natural crystalline growth)
Polish
N/A (Natural crystal faces)
Fluorescence
None visible under standard lighting
Inclusions
Visible feathering and internal crystal structures; potential garnet or mineral inclusion (small red speck)
Blemishes
Natural growth lines and surface percussion marks

Likely African (Botswana or South Africa) based on morphology
Treatment Detection
None apparent; looks completely natural
Estimated Value
$150 - $450 USD based on specimen quality
