Not applicable (Rough stone) Cut
Carat
Estimated 1.5 - 2.5 carats
Color
Near-colorless to white

Included / Industrial Grade
Shape
Rough Octahedral/Rounded Crystal
Overall Assessment
The specimen shown is a translucent, rounded rough mineral crystal held between fingers. Without professional gemological equipment (such as a thermal conductivity tester, refractometer, or spectroscopic analysis), it is impossible to definitively confirm if this is a raw diamond or another mineral such as quartz. Further physical testing is strongly recommended.
Cut Quality
Not applicable (Rough stone)
Brilliance
Low, due to lack of standard facet angles and rough surface
Fire
Minimal to none in current raw state
Scintillation
Poor, lacking precise facet patterns
Proportions
Natural crystal form, proportions do not apply
Symmetry
Natural crystal symmetry
Polish
Unpolished natural surface
Fluorescence
Cannot be determined visually without UV testing
Inclusions
Heavy internal cloudiness and crystal inclusions typical of raw stones
Blemishes
Natural surface pitting and irregularities
Origin
Alluvial or primary pipe deposit indicator
Treatment Detection
No obvious signs of artificial treatment; appears in natural state
Estimated Value
Nominal value as a mineral specimen unless confirmed as gemstone-quality rough diamond
Certification Estimate
Requires professional laboratory testing by GIA or similar institution for positive identification
Investment Potential
Low as a polished gem investment; moderate for mineral specimen collectors
Similar Diamonds
Ugly duckling industrial rough diamonds or raw quartz crystals
Setting Suggestions
Wire-wrapped or organic bezel setting to preserve raw aesthetic
Care & Maintenance
Store separately to prevent scratching other materials; clean with mild soapy water
Interesting Facts
Most diamonds are recovered in a rough, octahedral crystal form before undergoing precision cutting and polishing
