Natural rough crystal fragment or possibly quartz/glass simulant
Natural rough crystal fragment or possibly quartz/glass simulant · Uncut or heavily fractured rough fragment
Poor (uncut rough fragment with natural or broken surfaces) Cut
Carat
Rough visual estimate around 3.5 to 5.0 carats
Color
Colorless to near-colorless
Clarity
I3 (heavy inclusions and internal fracturing)
Shape
Uncut or heavily fractured rough fragment
Overall Assessment
The specimen displays irregular cleavage and fracture patterns characteristic of a raw mineral piece, requiring professional gemological testing (such as a thermal conductivity or Raman spectroscopy) to definitively separate diamond from quartz or glass simulants.
Cut Quality
Poor (uncut rough fragment with natural or broken surfaces)
Brilliance
Low due to lack of faceting and heavy internal fractures
Fire
Minimal dispersion visible due to raw structural state
Scintillation
Poor, lacking standard facet patterns for light return
Proportions
Not applicable to rough, irregular crystal fragments
Symmetry
Irregular / Asymmetrical
Polish
Raw or naturally weathered surface with rough fracture planes
Fluorescence
Cannot be definitively determined without UV testing
Inclusions
Extensive internal feathering, cleavage planes, and fractures
Blemishes
Surface chips, natural growth lines, and rough edges
Origin
Unknown natural rough mineral origin
Treatment Detection
No obvious enhancements; appears to be in a raw, unaltered state
Estimated Value
Nominal value as a mineral specimen rather than a gemstone
Certification Estimate
Unlikely to be certified by GIA or AGS due to industrial/rough quality
Investment Potential
None; primarily of educational or specimen interest
Similar Diamonds
Industrial-grade boart or low-quality rough diamond fragments
Setting Suggestions
Not suitable for standard jewelry settings unless wire-wrapped as a raw specimen
Care & Maintenance
Handle with care to prevent further breakage along natural cleavage planes
Interesting Facts
Raw crystals showcase the natural octahedral or distorted growth habits of minerals before human cutting and polishing
