Natural rough crystal
Natural rough crystal · Uncut octahedral or irregular crystal form
Not applicable (rough, uncut state) Cut
Carat
Estimated 2.5 to 3.5 carats
Color
Near-colorless to faint tint (approx. G-I range)
Clarity
Included (approx. SI1-SI2 range)
Shape
Uncut octahedral or irregular crystal form
Overall Assessment
An interesting natural rough crystal specimen with visible growth features and inclusions, offering potential for a unique custom-cut polished diamond
Cut Quality
Not applicable (rough, uncut state)
Brilliance
Limited in current rough state, restricted to windowing areas
Fire
Minimal dispersion observed due to rough surface and lack of facet angles
Scintillation
Absent in raw form; will develop upon proper faceting
Proportions
Rough elongated crystal morphology, non-standard proportions prior to cutting
Symmetry
Natural crystal symmetry, showing distorted growth lines and faces
Polish
Natural unpolished crystal faces with visible surface striations and etch channels
Fluorescence
Cannot be definitively determined visually without UV testing, likely Faint to None
Inclusions
Internal feather fractures, cloudiness, and dark mineral inclusions visible
Blemishes
Natural surface trigons, etch marks, and adhering matrix minerals along edges
Origin
Alluvial or primary kimberlite deposit origin
Treatment Detection
No signs of artificial treatment; completely natural rough specimen
Estimated Value
Varies widely based on yield potential post-cutting, roughly moderate wholesale value
Certification Estimate
GIA or similar major laboratory would grade post-cut; currently uncertified rough
Investment Potential
Moderate, primarily dependent on cutter's skill to maximize finished polished weight and clarity
Similar Diamonds
Typical run-of-mine industrial or commercial grade rough diamond crystals
Setting Suggestions
Best kept as a raw mineral specimen or custom designed in an organic bezel setting
Care & Maintenance
Store separately to prevent scratching other stones; clean gently with warm soapy water and a soft brush
