Overall Assessment
An intriguing natural rough diamond specimen with visible growth features, ideal for bespoke jewelry or mineral collections rather than standard investment stones.
Cut Quality
Not applicable (Rough, unpolished crystal)

Limited scintillation restricted to natural reflective crystal faces
Proportions
Natural elongated rough crystal proportions without standard facet angles
Symmetry
Natural asymmetrical crystal formation with strictions and growth lines
Polish
Natural unpolished crystal faces (trigons and natural surface textures)
Fluorescence
Cannot be definitively determined visually without UV testing, likely Faint to Medium
Inclusions
Heavy internal feathering, cloud formations, graining lines, and potential mineral inclusions
Blemishes
Natural surface etching, rough skin, chips, and irregular growth markings

Treatment Detection
No signs of artificial treatment; completely untreated natural rough
Estimated Value
$500 - $1,500 depending on final cut yield and purity
Certification Estimate
GIA or IDEX gemological laboratories for origin and weight verification

Moderate value primarily as collector mineral specimen or custom bespoke jewelry piece
Similar Diamonds
Comparable industrial or lower-gem-quality natural rough diamond crystals
Setting Suggestions
Raw crystal pendant setting in yellow gold or custom bezel-set ring showcasing natural form
