Natural rough diamond crystal
Natural rough diamond crystal · Rough elongated crystal (uncut, octahedral/dodecahedral fragment)
Not applicable (Rough, unpolished crystal specimen) Cut
Carat
Estimated 2.0 to 3.5 carats based on visual scale against fingers
Color
Near colorless to faint yellow/brown tint (approx. G-I range)
Clarity
Included (I1 to I2 range due to prominent internal fractures and dark inclusions)
Shape
Rough elongated crystal (uncut, octahedral/dodecahedral fragment)
Overall Assessment
An interesting, natural rough diamond crystal fragment showcasing raw geological features, well-suited for a mineral collection or custom organic jewelry piece rather than high-end faceted cutting.
Cut Quality
Not applicable (Rough, unpolished crystal specimen)
Brilliance
Low brilliance due to rough, unpolished surfaces and internal fractures
Fire
Minimal dispersion visible through rough, unpolished faces
Scintillation
Poor scintillation due to lack of standard facets and internal flaws
Proportions
Irregular natural crystal proportions, non-standard depth and table
Symmetry
Natural crystal symmetry, distorted growth habit with elongation
Polish
Natural crystal faces (trigons/growth lines present)
Fluorescence
Cannot be determined without UV testing (Likely none to faint blue)
Inclusions
Prominent dark mineral inclusions, internal feather fractures, and cloudiness
Blemishes
Natural surface pitting, rough skin, and growth striations
Origin
Natural alluvial or primary kimberlite deposit origin
Treatment Detection
No evidence of artificial treatments; completely natural state
Estimated Value
Modest value as a mineral specimen; rough industrial or lower-tier gem value (approx $100 - $300 USD)
Certification Estimate
GIA or local gemological laboratory as an uncertified rough diamond specimen
Investment Potential
Low investment potential for jewelry use, primarily valued by mineral collectors
Similar Diamonds
Typical run-of-mine industrial or low-clarity gem-grade rough diamond crystals
Setting Suggestions
Best preserved as a raw mineral specimen or custom organic/raw wire-wrap jewelry setting
Care & Maintenance
Handle with care to prevent breakage along natural cleavage planes; clean gently with warm soapy water
Interesting Facts
Displays natural growth lines and dark mineral inclusions often trapped during rapid mantle formation
