Likely Quartz, Glass, or Macle Rough Diamond
Likely Quartz, Glass, or Macle Rough Diamond · Rough / Uncut (Macle-like formation)
N/A (Uncut rough specimen) Cut
Carat
Estimated 25.0 - 50.0 carats based on finger scale
Color
Colorless (D-F range)
Clarity
I1-I2 due to significant internal fractures and cleavages
Shape
Rough / Uncut (Macle-like formation)
Overall Assessment
The specimen exhibits conchoidal fracture patterns more consistent with high-clarity quartz or glass than a gem-quality diamond. If diamond, it is high-color but low-clarity industrial rough.
Cut Quality
N/A (Uncut rough specimen)
Brilliance
Low (Internal light scattering due to fractures)
Fire
Minimal (Characteristic of non-gem materials or low-grade rough)
Scintillation
Diffuse (Reflections from flat surface planes only)
Proportions
Non-geometric (Irregular natural cleavage planes)
Symmetry
Poor (Natural irregular state)
Polish
N/A (Natural surfaces)
Fluorescence
Indeterminate from image
Inclusions
Conchoidal fractures, internal veining, and step-like growth features
Blemishes
Surface pitting and significant percussion marks
Origin
Secondary alluvial source if natural diamond
Treatment Detection
No obvious artificial coatings detected visually
Estimated Value
Minimal if glass/quartz; highly variable if industrial grade rough
Certification Estimate
Rough Diamond Evaluation would require GIA Rough Diamond Report
Investment Potential
Low (Material appears better suited for industrial use or as a specimen)
Similar Diamonds
Industrial grade Boart or large clear Quartz shards
Setting Suggestions
Wire wrap or custom primitive claw setting for specimen display
Care & Maintenance
Avoid impact; fractures make the stone susceptible to splitting
Interesting Facts
The 'V' shape suggests a macle twin crystal formation if this is a diamond
