Not Applicable (Rough, uncut stone) Cut
Carat
Estimated 2.5 to 3.5 carats
Color
Near Colorless to Light Brownish Tint (Estimated K-M range)
Clarity
I1 to I2 (Included, typical for raw diamond specimens with surface impurities and internal flaws)
Shape
Uncut / Rough Crystalline Form
Overall Assessment
An interesting and authentic natural rough diamond crystal specimen, valuable primarily for its raw geological form rather than faceted jewelry potential
Cut Quality
Not Applicable (Rough, uncut stone)
Brilliance
Low to moderate due to rough, unpolished exterior and lack of facet geometry
Fire
Minimal due to unfaceted surface scattering light irregularly
Scintillation
Absent due to lack of standard facet arrangement
Proportions
Irregular rough crystal proportions with no standard table or pavilion
Symmetry
Natural asymmetrical rough formation with curved crystal faces
Polish
Unpolished natural crystal surface with original growth lines and etch channels
Fluorescence
Unable to determine without UV testing (Likely Faint or None)
Inclusions
Abundant natural mineral inclusions, feathers, and cloud-like formations visible internally
Blemishes
Natural surface etch marks, cavities, trigons, and adhering matrix minerals
Origin
Likely alluvial or primary kimberlitic pipe deposit (African or South American origin common for specimens of this appearance)
Treatment Detection
No signs of artificial treatment; purely natural rough state
Estimated Value
Varies significantly as a specimen; typically lower per carat than polished stones, valued more by mineral collectors
Certification Estimate
GIA or similar major lab would issue a 'Rough Diamond Identification Report' rather than a standard grading report
Investment Potential
Collected more as a unique mineral specimen than a traditional financial investment
Similar Diamonds
Other natural industrial or specimen-grade rough diamond crystals
Setting Suggestions
Wire-wrapped pendant setting or custom organic bezel setting to preserve its raw crystal shape
Care & Maintenance
Store separately in a soft pouch to prevent scratching other softer stones; clean gently with warm soapy water and a soft brush
Interesting Facts
The curved striations and irregular surface features are natural growth phenomena known as dissolution or etching features formed deep within the Earth
