Overall Assessment
An interesting and genuine natural rough diamond crystal displaying characteristic transparency, natural etch channels, and inclusions, making it an appealing piece for mineral collectors and custom jewelers
Cut Quality
Not applicable for rough uncut specimen
Brilliance
Limited due to the rough, unpolished nature of the crystal faces
Fire
Minimal surface fire visible through the transparent window area
Scintillation
Low to moderate light return through natural cleavage planes and transparent zones
Proportions
Natural rough crystal proportions, not faceted
Symmetry
Natural asymmetric crystal growth morphology
Polish
Natural crystalline faces with rough textured matrix adhering to edges
Fluorescence
Indeterminate from visual assessment alone
Inclusions
Internal fracture lines, feathers, and tiny mineral crystals trapped within the matrix
Blemishes
Natural surface pitting, rough skin, and minor etching marks on the crystal faces

Likely alluvial or primary kimberlite/lamproite deposit origin
Treatment Detection
No signs of enhancement or treatment detected; appears entirely untreated
Estimated Value
Varies by weight and purity, roughly $300 - $800 as a raw collector specimen
