Natural rough diamond
Natural rough diamond · Uncut raw crystal (irregular octahedron/fragment)
Not applicable (rough, uncut stone) Cut
Carat
Estimated 2.5 - 3.5 carats
Color
Near-colorless to faint yellow (approx. G-J range)
Clarity
Included (approx. I1-I2)
Shape
Uncut raw crystal (irregular octahedron/fragment)
Overall Assessment
An interesting and tactile specimen of a natural rough diamond crystal, showcasing authentic growth features, natural surface textures, and raw geological character before lapidary intervention.
Cut Quality
Not applicable (rough, uncut stone)
Brilliance
Low (due to rough, unpolished surface acting as a lens rather than a reflector)
Fire
Minimal due to lack of standard facet angles
Scintillation
Absent in current rough state
Proportions
Natural rough proportions, deep untutored mass
Symmetry
Natural irregular crystal symmetry
Polish
Raw, unpolished natural crystal faces with growth lines and trigons
Fluorescence
Cannot be definitively determined without UV testing (likely none to faint)
Inclusions
Internal feather fractures, cloud inclusions, and carbon spots visible
Blemishes
Natural surface etch channels, growth lines, and indented natural facets
Origin
Alluvial or primary kimberlite pipe origin (impossible to pinpoint specific mine without advanced spectroscopy)
Treatment Detection
No signs of artificial treatment; completely natural state
Estimated Value
Varies widely based on potential yield if cut; raw specimens typically lower per carat than polished gems, roughly $500 - $1,500 total depending on internal cleavage
Certification Estimate
GIA or similar major lab would issue a Rough Diamond Identification Report
Investment Potential
Low to moderate for speculative cutting; collector value depends on aesthetic appeal of the raw crystal
Similar Diamonds
Standard industrial or lower-gem-quality rough diamond crystals
Setting Suggestions
Best set in a custom raw-stone bezel or wire-wrap pendant to preserve its organic, earthy aesthetic
Care & Maintenance
Store separately to avoid scratching softer materials, clean gently with warm soapy water and a soft brush
Interesting Facts
Rough diamonds retain the ancient geological memory of the Earth's mantle where they formed billions of years ago
