Natural rough diamond / crystalline mineral specimen with significant matrix inclusions
Natural rough diamond / crystalline mineral specimen with significant matrix inclusions · Uncut, irregular rough crystal / fragment
Not applicable (Rough, unpolished crystal fragment) Cut
Carat
Estimated 3.5 to 5.0 carats based on visual volume
Color
K-M range (off-white / tinted brown-gray)
Clarity
I3 (Included, heavily fractured with internal flaws and surface reaching inclusions)
Shape
Uncut, irregular rough crystal / fragment
Overall Assessment
This is a natural, unpolished rough diamond crystal fragment characterized by heavy inclusions, internal fractures, and an irregular shape. It possesses industrial or mineral specimen value rather than gem-grade commercial value, showcasing the raw geological reality of diamond formation before human modification.
Cut Quality
Not applicable (Rough, unpolished crystal fragment)
Brilliance
Very low due to lack of cut facets and heavy inclusions
Fire
Minimal to none due to lack of standard pavilion and crown angles
Scintillation
Absent due to raw, unfaceted surface texture
Proportions
Not applicable to raw rough material
Symmetry
Poor / Asymmetrical due to natural raw crystallization and fracture patterns
Polish
Unpolished natural crystal faces and fracture surfaces
Fluorescence
Cannot be definitively determined without UV testing, likely none to faint
Inclusions
Heavy internal clouding, feather fractures, carbon spots, and mineral inclusions trapped within the crystal lattice
Blemishes
Natural surface etchings, trigons (possibly), and rough fracture edges
Origin
Likely alluvial or primary pipe deposit from African, Russian, or South American rough diamond sources
Treatment Detection
No visible signs of artificial enhancement; Appears completely natural and untreated
Estimated Value
Nominal value as a mineral specimen or low-grade industrial diamond, ranging from $50 to $150 depending on exact weight and composition
Certification Estimate
Unlikely to be certified by major labs like GIA as a gem-quality diamond; more suited for industrial grade or mineral specimen authentication
Investment Potential
Low investment potential for resale; primarily of interest to mineral collectors or educational purposes
Similar Diamonds
Industrial grade rough diamond crystals, low-quality bort, or unrefined alluvial diamond specimens
Setting Suggestions
Wire-wrapped or organic bezel setting if desired to be worn as a raw mineral jewelry piece
Care & Maintenance
Store separately from other stones to prevent scratching, as raw crystal edges can be fragile along cleavage planes
Interesting Facts
Displays the raw, untreated state in which diamonds are mined before undergoing precision cutting and polishing by master gem cutters
