Natural rough crystal / Ice
Natural rough crystal / Ice · Rough elongated crystal (unfaceted)
Not Applicable (Uncut/Rough) Cut
Carat
Estimated 3.5 to 5.0 carats equivalent based on dimensions
Color
Colorless (D-F equivalent)
Clarity
Included (Contains internal fractures and surface irregularities)
Shape
Rough elongated crystal (unfaceted)
Overall Assessment
This appears to be a natural translucent elongated mineral crystal, exhibiting raw growth characteristics rather than a standard faceted gemstone. Further specialized testing (such as thermal conductivity or Raman spectroscopy) is required to definitively distinguish diamond from quartz, glass, or ice.
Cut Quality
Not Applicable (Uncut/Rough)
Brilliance
Vitreous reflection typical of raw transparent minerals
Fire
Limited dispersion due to lack of faceted cut angles
Scintillation
Minimal due to absence of standard pavilion and crown facets
Proportions
Elongated tabular habit typical of natural crystal formation
Symmetry
Natural asymmetric crystal growth
Polish
Raw, unpolished crystal faces
Fluorescence
Cannot determine without UV testing
Inclusions
Internal feather fractures, crystal growth lines, and inclusions visible
Blemishes
Natural surface trigons, etching channels, and roughness
Origin
Alluvial or primary kimberlite deposit indicator if diamond, or natural geological formation
Treatment Detection
No treatments detected; entirely raw state
Estimated Value
Nominal value as a mineral specimen; highly variable depending on material authenticity
Certification Estimate
Not applicable for un-cut rough specimens without lab submission
Investment Potential
Collector value as a mineral specimen rather than a standard investment diamond
Similar Diamonds
Unaltered rough diamond octahedral or elongated crystals
Setting Suggestions
Wire-wrapped pendant setting or custom prong mounting for raw crystal jewelry
Care & Maintenance
Handle with care to prevent chipping along cleavage planes; clean with warm soapy water and soft brush
