Rough natural diamond specimen (or potential quartz/agate matrix based on crystalline texture, but analyzing as raw crystalline material)
Rough natural diamond specimen (or potential quartz/agate matrix based on crystalline texture, but analyzing as raw crystalline material) · Rough crystal / Uncut natural form
Not applicable (uncut rough stone) Cut
Carat
Estimated 3.5 to 5.0 carats based on visual proportions in macro view
Color
Off-white / Light brown tint (K-M range)
Clarity
Included (I1-I3 equivalent for rough)
Shape
Rough crystal / Uncut natural form
Overall Assessment
An interesting raw crystalline specimen displaying natural surface textures. Further gemological testing (such as thermal conductivity or Raman spectroscopy) is recommended to definitively confirm diamond versus quartz or other matrix minerals.
Cut Quality
Not applicable (uncut rough stone)
Brilliance
Low to moderate due to raw, unpolished surface scatter
Fire
Obscured by surface texture; minimal dispersion visible
Scintillation
Minimal to none in current rough state
Proportions
Natural unmodified crystal habit
Symmetry
Natural asymmetric crystal growth
Polish
Raw, unpolished natural surface with typical rough crystal texture
Fluorescence
Cannot determine accurately without UV light testing (typically Medium Blue in many natural roughs)
Inclusions
Heavy internal clouding, feathers, and micro-fractures typical of raw mineral specimens
Blemishes
Natural surface pitting, trigons, and rough skin typical of alluvial or primary deposit rough
Origin
Likely alluvial deposit or primary kimberlitic/lamproitic matrix
Treatment Detection
No signs of enhancement; entirely untreated natural state
Estimated Value
Nominal value as a mineral specimen ($50 - $200 USD depending on true composition and weight)
Certification Estimate
GIA or specialized rough diamond evaluation certificate
Investment Potential
Low investment value; primarily of interest to mineral collectors or lapidary hobbyists
Similar Diamonds
Standard industrial or low-gem-quality natural diamond rough parcels
Setting Suggestions
Raw mineral bezel setting or organic wire-wrapped pendant to preserve natural aesthetic
Care & Maintenance
Store separately from other jewelry to prevent scratching softer metals; clean with warm soapy water and a soft brush
Interesting Facts
Raw diamonds often resemble ordinary pebbles or frosted glass before being cut and polished by master lapidaries
