Natural Rough Diamond or Quartz crystal (Visual appearance mimics a rough diamond macle or crystal specimen)
Natural Rough Diamond or Quartz crystal (Visual appearance mimics a rough diamond macle or crystal specimen) · Natural Rough / Uncut
None (Rough/Uncut) Cut
Carat
Estimated 2.0 - 5.0 carats based on visual scale
Color
Near Colorless to Faint Yellow (G-J range equivalent)
Clarity
Included (I1-I2 equivalent due to heavy internal feathers and glass-like fractures)
Shape
Natural Rough / Uncut
Overall Assessment
This is a natural mineral specimen, likely a rough diamond with significant internal inclusions and irregular growth patterns. Its value is limited by its industrial-leaning clarity and lack of a symmetric crystal habit.
Cut Quality
None (Rough/Uncut)
Brilliance
Low (Surface reflections only, no light return from facets)
Fire
Weak (Visible dispersion only at specific edges)
Scintillation
Low (Lacks faceted scintillation)
Proportions
Irregular natural formation with conchoidal-style fractures
Symmetry
N/A (Natural irregular growth)
Polish
N/A (Natural crystal faces)
Fluorescence
Indeterminate without UV light
Inclusions
Prominent internal feathers, cleavage planes, and heavy twinning lines
Blemishes
Surface percussion marks and natural growth striations
Origin
Likely alluvial source from Africa or Brazil
Treatment Detection
None apparent; looks like a raw natural mineral
Estimated Value
$150 - $400 (Specimen value rather than gem-cut value)
Certification Estimate
GIA Rough Diamond Grading Report (Likely I-grade clarity)
Investment Potential
Low; primarily a collector's specimen rather than a financial asset
Similar Diamonds
Herkimer Diamonds (Quartz) or lower-grade industrial rough stones
Setting Suggestions
Wire-wrapped necklace or a custom rough-diamond 'claw' setting in 14k gold
Care & Maintenance
Avoid ultrasonic cleaners; clean with mild soap and a soft brush to prevent dirt buildup in deep surface fissures
Interesting Facts
Rough diamonds often show 'trigons' or triangular growth marks on the surface, which are faintly visible in this texture.
