Natural rough diamond / mineral specimen, appearing heavily included or potentially industrial-grade material / quartz surrogate
Natural rough diamond / mineral specimen, appearing heavily included or potentially industrial-grade material / quartz surrogate · Uncut rough / irregular crystal form with natural faces
Not applicable (Rough, unpolished stone) Cut
Carat
Estimated 3.5 to 5.0 carats based on visual size relative to fingers
Color
Low color grade or tinted brown/grey due to heavy impurities
Clarity
I3 / Industrial grade with prominent black inclusions and opaque surface patches
Shape
Uncut rough / irregular crystal form with natural faces
Overall Assessment
An interesting raw mineral specimen showing natural crystal texture and heavy inclusions, possessing more value as a raw educational piece than as a polished gemstone.
Cut Quality
Not applicable (Rough, unpolished stone)
Brilliance
Very low due to lack of facets and surface texture
Fire
Negligible in current rough state
Scintillation
Minimal to none
Proportions
Non-standard rough geometry
Symmetry
Asymmetrical natural crystal growth
Polish
Unpolished natural rough surface
Fluorescence
Unknown / Untested without UV light
Inclusions
Heavy dark carbon spots and internal cloudiness
Blemishes
Rough surface pitting, natural etch channels, and irregular texture
Origin
Alluvial or primary kimberlite rough origin
Treatment Detection
No treatments detected; completely untreated natural state
Estimated Value
Nominal value as a raw specimen, very low gem-quality market value
Certification Estimate
Industrial or uncertified mineral specimen report
Investment Potential
Minimal investment value, sold primarily as a curiosity or specimen
Similar Diamonds
Industrial grade boart or low-quality alluvial rough diamonds
Setting Suggestions
Wire-wrapped rough stone pendant or preserved as a mineral specimen
Care & Maintenance
Store in a soft pouch away from harder gemstones to prevent chipping of fragile rough edges
Interesting Facts
Most diamonds mined are of industrial grade rather than gem quality, used primarily for cutting, grinding, and drilling tools
