Natural diamond crystal (uncut, rough mineral specimen)
Natural diamond crystal (uncut, rough mineral specimen) · Irregular rough crystal with octahedral/cubic tendencies
Not applicable (uncut rough crystal) Cut

Carat
Estimated 3.5 to 5.0 carats based on rough visual scale
Color
Near colorless to faint yellow (approx. G-J range)
Clarity
Included (approx. I1-I2) due to internal fractures, inclusions, and feathering
Shape
Irregular rough crystal with octahedral/cubic tendencies
Overall Assessment
An interesting, tactile natural rough diamond crystal displaying raw geological features, growth striations, and matrix attachment areas, ideal for mineral collectors or custom organic jewelry designers.
Cut Quality
Not applicable (uncut rough crystal)
Brilliance
Limited due to rough surface and internal fracturing
Fire
Obscured by rough, untreated state
Scintillation
Minimal until cut and polished
Proportions
Natural rough proportions, unpolished and uncut
Symmetry
Natural crystal asymmetry with distorted growth planes
Polish
Raw, unpolished natural crystal faces showing striations and trigons
Fluorescence
Unknown without UV testing, likely None to Faint
Inclusions
Internal fractures, cloudiness, feathers, and potential mineral inclusions
Blemishes
Natural surface textures, pitting, and growth lines
Origin
Alluvial or primary kimberlite pipe deposit rough diamond
Treatment Detection
No treatments detected; completely natural raw state
Estimated Value
Nominal value as a rough mineral specimen, highly dependent on cutting yield (potentially $200-$600 as rough mineral)
Certification Estimate
GIA or similar major lab would grade it as a rough specimen or industrial/gem-grade parcel component
Investment Potential
Collector value for mineral specimens; moderate investment as a raw gemstone depending on potential cut yield
Similar Diamonds
Other alluvial rough diamond crystals of comparable size and clarity
Setting Suggestions
Raw mineral jewelry setting such as wire-wrapping or an organic bezel setting in yellow gold
Care & Maintenance
Store separately to avoid scratching other gems; clean gently with warm soapy water and a soft brush
