Overall Assessment
This is a genuine natural rough diamond crystal displaying classic raw characteristics including growth marks and surface features. While currently in an unpolished state, it holds potential for a custom-cut faceted gemstone or could be kept in its raw form for unique jewelry design.
Cut Quality
Not Applicable (Rough stone, unpolished)
Brilliance
Low due to lack of facets and rough exterior surface
Fire
Minimal dispersion visible through the raw surface
Scintillation
Poor due to unpolished and frosted natural faces
Proportions
Natural uncut proportions with uneven thickness and natural skin
Symmetry
Natural irregular symmetry characteristic of raw crystal growth
Polish
Raw natural crystal faces (octahedral growth lines and striations visible)
Fluorescence
Cannot be determined without UV light testing (Likely Faint to Medium Blue if natural)
Inclusions
Visible dark mineral spots, internal clouds, and feathery fractures
Blemishes
Natural surface etch channels, trigons, and rough skin textures
Origin
Likely alluvial or primary kimberlite pipe deposit (Africa, Canada, or Russia)
Treatment Detection
No treatments detected; completely untreated natural rough stone
Estimated Value
Depends heavily on yield after cutting, rough value approximately $200 - $600 USD
Certification Estimate
GIA or similar major lab would grade it as a rough industrial/gem-grade parcel stone
Investment Potential
Moderate to low as a single rough stone; value is speculative until cut and polished
Similar Diamonds
Other unpolished alluvial rough diamond crystals of comparable size
Setting Suggestions
Organic raw diamond pendant setting or custom bezel setting celebrating the natural form
Care & Maintenance
Store separately to avoid scratching other jewelry; clean gently with warm soapy water and a soft brush
Interesting Facts
The surface features visible on the stone, such as growth lines and striations, are formed deep within the Earth's mantle over billions of years
