Natural
Natural · Rough crystal (uncut octahedral / elongated fragment)
Not applicable (Rough, unpolished crystal specimen) Cut

Carat
Estimated 3.5 to 4.5 carats based on visual proportions and finger scale
Color
Near Colorless to faint tint (approx. G-I range)
Clarity
SI2 to I1 due to natural surface features and internal irregularities
Shape
Rough crystal (uncut octahedral / elongated fragment)
Overall Assessment
An interesting and sizable natural rough diamond crystal displaying classic geological growth characteristics, offering potential for custom cutting or preservation as a unique mineral specimen.
Cut Quality
Not applicable (Rough, unpolished crystal specimen)
Brilliance
Moderate due to rough exterior and lack of standard facet geometry
Fire
Limited dispersion due to rough, unpolished state
Scintillation
Minimal flash effect, limited by natural unfaceted surfaces
Proportions
Natural rough dimensions, elongated morphology, no standard table or pavilion angles
Symmetry
Natural crystal symmetry (elongated trigonal/hexagonal morphology with striations)
Polish
Natural crystal faces (etched growth features and trigons visible)
Fluorescence
Indeterminate from visual assessment alone (requires UV testing)
Inclusions
Natural feathers, mineral crystals, and cloud-like internal formations typical of rough diamond
Blemishes
Natural growth lines, trigons, and surface pitting intrinsic to rough diamond crystals
Origin
Likely alluvial or primary kimberlite pipe deposit (Africa, Canada, or Russia)
Treatment Detection
No signs of artificial treatment; completely natural rough specimen
Estimated Value
Varies widely depending on internal purity after cutting, roughly $1,500 - $3,500 USD in rough state
Certification Estimate
GIA (Gemological Institute of America) as a rough gem-quality diamond report
Investment Potential
Good potential for collectors of mineral specimens or custom lapidary artists
Similar Diamonds
Comparable natural rough octahedral and elongated gem-grade diamond crystals
Setting Suggestions
Custom organic prong setting or raw crystal wire-wrap to preserve natural aesthetic
Care & Maintenance
Handle with care to prevent chipping along cleavage planes; clean with warm soapy water and soft brush
Interesting Facts
Rough diamonds display natural growth features such as trigons (triangular depressions) formed by natural dissolution processes deep within the earth
