Natural (Rough Crystal)
Natural (Rough Crystal) · Rough Elongated Octahedron / Crystal Fragment
Not Applicable (Uncut Rough Specimen) Cut
Carat
Estimated 2.0 to 3.5 carats based on visual scale
Color
Near Colorless to Faint Yellow (I-J equivalent)
Clarity
Included (I1-I2 equivalent due to prominent internal feathers, clouds, and mineral inclusions)
Shape
Rough Elongated Octahedron / Crystal Fragment
Overall Assessment
This is an authentic, natural rough diamond crystal in an elongated prismatic habit. While its low clarity and heavy internal fractures make it unsuitable for high-end traditional jewelry in its current state, it possesses significant geological and educational charm as a raw mineral specimen.
Cut Quality
Not Applicable (Uncut Rough Specimen)
Brilliance
Low to Moderate due to rough, unpolished surface scattering light
Fire
Minimal in current rough state; will display standard diamond dispersion once properly faceted
Scintillation
Poor in rough state; blocked by surface texture and internal fractures
Proportions
Not Applicable (Rough crystal habit)
Symmetry
Natural Crystal Symmetry (Distorted Elongated Form)
Polish
Natural Unpolished Crystalline Surface (Growth lines and striations visible)
Fluorescence
Cannot be determined without UV testing (Likely Inert to Medium Blue)
Inclusions
Prominent internal feather fractures, clouds, and possible localized mineral inclusions or internal graining
Blemishes
Natural surface etch channels, trigons, and rough crystal skin textures
Origin
Alluvial or primary kimberlite deposit origin (African or Canadian rough source likely)
Treatment Detection
No signs of artificial treatment; completely natural untreated rough crystal
Estimated Value
Modest collector or specimen value ($100 - $300 USD), highly dependent on cutting yield if faceted
Certification Estimate
GIA or AGS would classify it as a rough industrial or low-gem quality diamond crystal specimen
Investment Potential
Low for resale as jewelry stone unless expertly custom-cut; moderate appeal for mineral specimen collectors
Similar Diamonds
Other low-clarity industrial or specimen-grade rough diamond crystals
Setting Suggestions
Raw uncut diamond jewelry in a protective bezel or cage setting, preferably in yellow or white gold
Care & Maintenance
Store separately to avoid scratching other gems; clean gently with warm soapy water and a soft brush
Interesting Facts
The parallel growth lines and striations visible on the surface are natural crystal growth features typical of rough diamond formation deep in the Earth's mantle
