Overall Assessment
This is a fascinating, unpolished natural diamond crystal featuring a prominent mineral inclusion patch. While unsuitable for traditional high-end jewelry due to heavy inclusions and lack of standard cut, it holds high educational and specimen appeal for collectors of natural minerals.
Cut Quality
Not Applicable (Rough, uncut stone)
Brilliance
Low to Moderate due to opacity and heavy internal interruptions
Fire
Very limited, obscured by rough surfaces and heavy inclusions
Scintillation
Minimal, localized to specific reflective crystal faces
Proportions
Not Applicable for rough stones (no table, crown, or pavilion facets)
Symmetry
Natural crystal symmetry showing distortion and uneven growth
Polish
Raw, natural crystal faces (some may exhibit natural trigons or striations)
Fluorescence
Cannot be definitively determined without UV testing, likely Inert to Faint
Inclusions
Large prominent brown/clay mineral inclusion pocket, internal feathers, clouds, and fractures
Blemishes
Natural surface roughness, etching marks, and irregular cleavage planes
Origin
Natural African or South American alluvial/primary deposit rough

Estimated Value
Low commercial value as a gemstone; valued primarily as a mineral specimen or collector's rough ranging from $50 to $200 depending on exact weight and locality
Certification Estimate
GIA or similar major lab would issue a Colored Diamond / Rough Stone Identification Report noting heavy inclusions
Investment Potential
Minimal monetary investment potential; collectible value only for mineral enthusiasts
Similar Diamonds

Setting Suggestions
Best preserved in its natural rough state using wire-wrapping or custom organic prong settings for rustic jewelry
Care & Maintenance
Avoid harsh ultrasonic cleaners due to internal fractures; clean gently with warm soapy water and a soft brush
