Natural rough diamond crystal showing distinct irregular formation with natural surface textures and included material.
Natural rough diamond crystal showing distinct irregular formation with natural surface textures and included material. · Rough / Uncut crystal with natural octahedral or distorted crystal faces.
Not applicable as this is a rough, un-faceted stone. Cut
Carat
Estimated between 5.00 to 8.00 carats based on visual proportions relative to human fingers.
Color
Estimated in the lower commercial color range, approximately J-K or tinted with brownish/yellowish hues.
Clarity
I2 to I3 due to prominent internal inclusions, fractures, and surface-reaching features.
Shape
Rough / Uncut crystal with natural octahedral or distorted crystal faces.
Overall Assessment
An interesting, large natural rough crystal with significant inclusions and surface staining. While not suitable for high-end jewelry in its current state, it possesses geological charm as an unworked diamond specimen.
Cut Quality
Not applicable as this is a rough, un-faceted stone.
Brilliance
Limited brilliance due to lack of standard facet geometry and presence of internal fractures.
Fire
Minimal spectral dispersion observable in its current un-faceted and included state.
Scintillation
Low scintillation; light is largely scattered or trapped by internal inclusions rather than reflected evenly.
Proportions
Irregular raw crystal geometry; standard pavilion, crown, and table measurements do not apply.
Symmetry
Natural asymmetric crystal growth typical of rough alluvial or primary deposit diamonds.
Polish
Raw, unpolished natural crystal faces showing striations (trigons or growth lines).
Fluorescence
Cannot be definitively determined without UV testing; likely inert to faint.
Inclusions
Heavy internal feather fractures, dark carbon spots, and localized brownish/reddish staining within fissures.
Blemishes
Natural surface etch channels, pits, and rough texture areas along the crystal skin.
Origin
Likely alluvial deposit origin, potentially from African or South American sources.
Treatment Detection
No signs of artificial treatment; appears completely untreated and in its natural mined state.
Estimated Value
Valued primarily as rough mineral specimen or industrial-grade material, ranging from $100 to $300 per carat depending on cutter assessment.
Certification Estimate
GIA or similar major lab would grade it as a natural industrial or low-gem quality rough diamond.
Investment Potential
Low investment potential for resale as a gemstone; primarily holds value as a unique mineral specimen or collector's rough.
Similar Diamonds
Comparable to un-cut industrial or low-grade gem rough sold in mineral markets.
Setting Suggestions
Best showcased in a raw, organic-style wire-wrap or bespoke bezel setting designed to preserve its natural rough aesthetic.
Care & Maintenance
Store separately to prevent scratching other stones; clean gently with warm soapy water and a soft brush; avoid harsh ultrasonic cleaners due to internal fractures.
Interesting Facts
Rough diamonds like this showcase the natural, unaltered geometry straight from the Earth before human cutting and polishing.
