Natural rough diamond crystal or potentially an untreated quartz crystal with earthy matrix, requiring formal gemological testing to definitively separate from diamond.
Natural rough diamond crystal or potentially an untreated quartz crystal with earthy matrix, requiring formal gemological testing to definitively separate from diamond. · Uncut natural crystal form (Rough / Irregular crystal elongation)
Not applicable (Uncut rough specimen) Cut
Carat
Estimated 2.0 to 3.5 carats based on visual proportions and density assumptions
Color
Light brown to yellowish tint with surface staining (Fancy Light Brown / Near Colorless base)
Clarity
I2 to I3 (Included with prominent surface fractures, cloudiness, and included matrix material)
Shape
Uncut natural crystal form (Rough / Irregular crystal elongation)
Overall Assessment
This specimen displays the raw, unpolished characteristics of a natural crystalline mineral. Professional laboratory testing (such as thermal conductivity or infrared spectroscopy) is strongly recommended to confirm true diamond identity versus quartz or other simulants.
Cut Quality
Not applicable (Uncut rough specimen)
Brilliance
Low due to lack of standard facet angles and heavy surface/internal impurities
Fire
Minimal dispersion observed due to rough surfaces and internal clouding
Scintillation
Limited flash effect primarily from natural crystal window areas
Proportions
Natural uncut proportions with irregular depth and girdle equivalent
Symmetry
Natural asymmetrical crystal growth
Polish
Natural unpolished crystal faces with rough texture and surface etching
Fluorescence
Indeterminate from visual inspection alone (typically tested with long-wave UV)
Inclusions
Heavy internal feathers, clouds, and embedded mineral/earthy inclusions
Blemishes
Surface naturals, pits, and abrasion marks from alluvial or matrix extraction
Origin
Likely alluvial or primary pipe deposit origin, typical of unworked rough stones
Treatment Detection
No evidence of artificial enhancement; appears completely untreated and in its natural state
Estimated Value
Nominal value as a mineral specimen; significantly lower if testing reveals quartz rather than diamond
Certification Estimate
GIA or similar major lab report for rough certification or preliminary weight verification
Investment Potential
Low as a liquid financial asset; primarily valued by collectors of raw minerals or custom jewelry designers
Similar Diamonds
Other natural unworked octahedral or irregular rough diamond crystals
Setting Suggestions
Best suited for organic wire-wrapped raw gemstone jewelry or bespoke rustic bezel settings
Care & Maintenance
Avoid harsh chemical cleaners and ultrasonic baths; clean gently with warm soapy water and a soft brush
