Overall Assessment
This is a raw, uncut natural diamond crystal in its matrix or rough state, highly valued for geological and specimen display purposes rather than jewelry use.
Cut Quality
Not Applicable (Rough, uncut stone)
Brilliance
Low due to lack of faceting and opaque rough exterior
Fire
Minimal to none in current rough state
Scintillation
Not applicable for uncut rough stone
Proportions
Natural rough proportions; undefined table and depth due to lack of faceting
Symmetry
Natural crystalline symmetry showing growth lines and octahedral faces
Polish
Natural unpolished crystal skin and cleavage surfaces
Fluorescence
Cannot be determined without UV testing (likely Faint to Medium Blue)
Inclusions
Heavy internal clouding, feathers, and dark mineral inclusions visible
Blemishes
Natural surface trigons, rough skin, and minor surface breaking fractures
Origin
Alluvial or primary kimberlite pipe deposit (Africa or Canada rough type)

No signs of enhancement or treatment; completely natural
Estimated Value
$100 - $300 as a raw mineral specimen
Certification Estimate
GIA or similar major lab would grade as Natural Rough Diamond specimen
