Natural rough diamond specimen
Natural rough diamond specimen · Rough crystal shard / Untutored
Not Applicable (Rough, uncut stone) Cut
Carat
Estimated 2.50 to 3.50 carats based on rough dimensions
Color
Estimated G-H (Near Colorless)
Clarity
Estimated SI2 to I1 due to visible internal fracturing and feathering
Shape
Rough crystal shard / Untutored
Overall Assessment
An intriguing natural rough diamond specimen showing classic growth lines and rough cleavage planes, offering potential for either custom raw jewelry design or professional cutting
Cut Quality
Not Applicable (Rough, uncut stone)
Brilliance
Subdued due to unpolished and rough nature of the exterior surfaces
Fire
Limited light dispersion resulting from untreated rough crystal faces
Scintillation
Minimal play of light prior to cutting and faceting
Proportions
Natural uncut crystal form, proportions dictated by geologic formation rather than optical precision
Symmetry
Natural octahedral distortion / Irregular crystal symmetry
Polish
Natural crystal faces displaying striktionen and growth lines (trigons potentially present)
Fluorescence
Cannot be definitively determined without UV testing, likely Faint to Medium
Inclusions
Internal feathers, cloudiness, and minor carbon spots typical of natural rough stones
Blemishes
Natural surface etching, trigons, and irregular fracture planes
Origin
Likely alluvial or primary kimberlite pipe origin (African or Canadian sources are common)
Treatment Detection
No treatments detected; exhibits completely natural geological formation features
Estimated Value
Varies widely from $3,000 to $6,000 depending on cutting yield potential and internal inclusions
Certification Estimate
GIA (Gemological Institute of America) as a natural rough diamond report
Investment Potential
Moderate to high speculative value if retained as a unique mineral specimen or custom-cut into a polished stone
Similar Diamonds
Comparable natural uncut industrial or gem-grade diamond crystal rough
Setting Suggestions
Can be set raw in a custom organic bezel or prong setting, or cut into a brilliant round or cushion shape
Care & Maintenance
Store separately to prevent scratching other jewelry; clean gently with warm soapy water and a soft brush
Interesting Facts
The striations visible on the surface are growth lines formed deep within the Earth's mantle under intense pressure and temperature
