Natural diamond in rough crystal form
Natural diamond in rough crystal form · Rough crystal / Uncut octahedron fragment
Not applicable (Rough uncut stone) Cut
Carat
Estimated 3.5 to 5.0 carats
Color
Near-colorless to light brown/champagne tint
Clarity
Included (I1/I2 grade based on internal features and surface wear)
Shape
Rough crystal / Uncut octahedron fragment
Overall Assessment
An interesting specimen of a natural rough diamond showing classic surface textures, etchings, and inclusions, best suited for bespoke raw-stone jewelry or mineral collection
Cut Quality
Not applicable (Rough uncut stone)
Brilliance
Low to moderate due to rough surfaces and lack of faceted optics
Fire
Minimal due to uncut state and surface wear
Scintillation
Poor, as light does not return through precise pavilion facets
Proportions
Not applicable for rough stones; natural morphology displays distorted octahedral/dodecahedral growth lines
Symmetry
Natural irregular crystal symmetry
Polish
Unpolished natural crystal faces and cleavage planes
Fluorescence
Indeterminate from visual observation alone (requires UV testing)
Inclusions
Internal cloud-like clusters, micro-fractures, and mineral crystal inclusions visible
Blemishes
Surface naturals, etch channels, scratches, and pitting along cleavage planes
Origin
Likely alluvial deposit origin due to surface abrasion and rounding of edges
Treatment Detection
No visible evidence of artificial treatments; appears completely untreated and natural
Estimated Value
Varies widely based on industrial versus gem-quality potential, roughly $500 - $1,500 depending on cutting yield
Certification Estimate
GIA or similar major gemological laboratory would issue a rough diamond report
Investment Potential
Moderate; primarily holds value as a collector specimen or custom jewelry piece rather than standard investment stones
Similar Diamonds
Other alluvial rough diamond crystals of comparable size and clarity
Setting Suggestions
Raw crystal pendant or bespoke organic bezel setting to preserve its natural form
Care & Maintenance
Store separately to prevent scratching other stones; clean gently with warm soapy water and a soft brush
Interesting Facts
Rough diamonds display natural growth features like trigons and striations formed deep within the Earth's mantle over billions of years
