Natural rough diamond showing a distinct octahedral crystal shape.
Natural rough diamond showing a distinct octahedral crystal shape. · Rough Octahedron
Not applicable as this is an uncut, natural rough crystal. Cut
Carat
Estimated at 0.50 to 0.75 carats based on visual scale against human fingers.
Color
Translucent to milky white with potential near-colorless areas.
Clarity
Included (I1-I3 equivalent for rough) due to numerous internal cloud-like formations and feathers.
Shape
Rough Octahedron
Overall Assessment
An interesting, natural rough diamond crystal displaying its native octahedral form, well-suited for collectors or unique raw-stone jewelry designs rather than traditional high-end faceted markets.
Cut Quality
Not applicable as this is an uncut, natural rough crystal.
Brilliance
Low to moderate due to translucent rough exterior and lack of faceted optical design.
Fire
Minimal, masked by the translucent and milky nature of the rough stone.
Scintillation
Limited flash effect primarily from natural crystal faces rather than internal facets.
Proportions
Natural crystal growth proportions; unshaped.
Symmetry
Natural crystal symmetry exhibiting octahedral faces.
Polish
Natural rough crystal faces; unpolished.
Fluorescence
Indeterminate from visual inspection alone; typically tested under UV light.
Inclusions
Internal clouds, pinpoint crystals, and minor feather fractures visible within the matrix.
Blemishes
Natural surface trigons and growth lines on the crystal faces.
Origin
Alluvial or primary kimberlite deposit origin; undetermined exact geographic location.
Treatment Detection
No signs of artificial enhancement or treatment observed; entirely natural state.
Estimated Value
Modest value reflecting industrial or low-grade gem rough market pricing.
Certification Estimate
GIA or similar major lab could issue a rough diamond report confirming natural origin.
Investment Potential
Low investment liquidity; valued primarily as a geological specimen or for custom raw jewelry pieces.
Similar Diamonds
Comparable to standard industrial or lower-quality ornamental rough diamond crystals.
Setting Suggestions
Best preserved as a raw mineral specimen, or mounted in a bespoke organic bezel setting (e.g., yellow gold or platinum).
Care & Maintenance
Standard jewelry cleaning with mild soap, warm water, and a soft brush; protect from hard impacts.
Interesting Facts
The octahedral shape is the classic crystal habit of diamond, forming deep within the Earth's mantle under extreme pressure and temperature.
