Overall Assessment
This specimen is a raw, uncut natural diamond crystal displaying typical rough features, requiring professional cutting and polishing to reveal gem-quality optical properties.
Cut Quality
Not Applicable (Uncut Rough Specimen)
Brilliance
Low to Moderate due to lack of standard facet angles and rough surface finish
Fire
Minimal dispersion observed due to rough, unpolished optical surfaces
Scintillation
Poor light return and flash due to absence of precise facet alignment
Proportions
Natural uncut proportions with deep raw pavilion and uneven natural crown facets
Symmetry
Asymmetrical Natural Crystal Habit
Polish
Unpolished Natural Crystal Faces (Trigons and Striations visible)
Fluorescence
Indeterminate from visual inspection
Inclusions
Extensive internal feathering, clouding, and mineral inclusions visible beneath the surface
Blemishes
Natural surface pitting, rough skin, striations, and indented naturals
Origin
Alluvial or primary kimberlite deposit origin; natural rough uncut state.
Treatment Detection
No signs of enhancement or treatment; completely untreated natural rough mineral state.
Estimated Value
Valued primarily as rough specimen or industrial/low-gem grade material, approximately $300 - $600 USD depending on cutter yield potential.
Certification Estimate
Gemological laboratories would classify this as an uncut natural diamond rough, requiring cutting to receive standard 4Cs grades.
Investment Potential
Low investment potential for standard resale; primarily valuable to collectors of rough minerals or diamond cutters assessing yield.
Similar Diamonds
Standard industrial or low-grade gem rough diamond crystals of comparable weight.
Setting Suggestions
Raw uncut diamond pendant or organic bespoke prongs preserving the natural crystal face.
Care & Maintenance
Store separately to avoid scratching other gems; clean with mild soapy water and a soft brush.
Interesting Facts
The surface shows natural growth features such as striations and triangular growth marks called trigons, typical of undisturbed diamond crystallization.
