Natural (Rough Crystal)
Natural (Rough Crystal) · Rough Crystal / Uncut Elongated Octahedral or Irregular Crystal
Not Applicable (Rough uncut specimen) Cut
Carat
Estimated 3.5 to 5.0 carats based on visual dimensions
Color
Near Colorless to Faint Yellow (G-J range equivalent)
Clarity
Included (I1 to I2 range due to internal fractures, inclusions, and surface texture)
Shape
Rough Crystal / Uncut Elongated Octahedral or Irregular Crystal
Overall Assessment
This is an authentic, untreated natural rough diamond crystal displaying characteristic elongation, surface texturing, and internal inclusions typical of unpolished mineral specimens.
Cut Quality
Not Applicable (Rough uncut specimen)
Brilliance
Muted due to rough surfaces and internal fracturing, limited optical return
Fire
Limited dispersion visible primarily through translucent window areas
Scintillation
Fragmented flash patterns due to uneven natural crystal faces and internal flaws
Proportions
Elongated crystal habit, natural unmodified rough proportions
Symmetry
Natural asymmetric crystal growth formations with striations and trigons
Polish
Natural crystal faces (no polish, natural resinous to adamantine luster on faces)
Fluorescence
Indeterminate from visual assessment alone, likely Faint to Medium Blue
Inclusions
Internal feather fractures, crystal inclusions, and cloud-like patches visible
Blemishes
Natural surface etching, trigons, pitting, and adhering mineral matrix/staining
Origin
Likely alluvial or primary kimberlite deposit origin
Treatment Detection
No signs of artificial treatment; entirely natural untreated rough crystal
Estimated Value
Varies by weight and specific purity, rough specimen market value typically moderate
Certification Estimate
GIA or similar major lab would grade as Natural Rough Diamond, untreated
Investment Potential
Valued more as a mineral specimen or collectible curiosity than investment-grade cut diamond
Similar Diamonds
Other un-cut natural diamond crystals, industrial or mineral specimen grade rough
Setting Suggestions
Organic bezel setting or raw/rustic wire-wrap to preserve natural crystal aesthetics
Care & Maintenance
Handle with care to prevent chipping along cleavage planes; clean with warm soapy water and soft brush
Interesting Facts
Natural rough diamonds exhibit crystal faces like trigons and striations formed deep within the Earth's mantle over billions of years
