Not a diamond; this specimen appears to be raw quartz crystal or optical glass with significant internal fractures and trapped mineral inclusions.
Not a diamond; this specimen appears to be raw quartz crystal or optical glass with significant internal fractures and trapped mineral inclusions. · Raw, unpolished crystal fragment with irregular fracture surfaces.
Not applicable (uncut raw mineral specimen). Cut
Carat
Estimated around 15-20 carats based on visual scale, though not applicable as a gemstone.
Color
Colorless with brown/yellow matrix inclusions.
Clarity
Included (heavy internal fractures, stress lines, and mineral pockets visible).
Shape
Raw, unpolished crystal fragment with irregular fracture surfaces.
Overall Assessment
This specimen is a fascinating raw mineral or glass fragment showing striking internal fractures and inclusions, but it holds no gemological or monetary value as a diamond.
Cut Quality
Not applicable (uncut raw mineral specimen).
Brilliance
Low to moderate due to massive internal fracturing diffusing light.
Fire
Minimal dispersion due to lack of precision facet geometry.
Scintillation
Poor, lacking standard facet reflections.
Proportions
Not applicable for raw mineral specimens.
Symmetry
Asymmetrical due to natural crystal growth and cleavage fractures.
Polish
Unpolished natural rough surface showing conchoidal fracture lines.
Fluorescence
Cannot be determined accurately without UV testing.
Inclusions
Heavy internal feather fractures, metallic-appearing dendritic or trapped matrix inclusions.
Blemishes
Natural surface etching, rough edges, and breakage facets.
Origin
Natural geological origin (likely pegmatite quartz pocket) or industrial slag/glass.
Treatment Detection
No obvious enhancements, appears completely natural or as-found.
Estimated Value
Nominal value as a mineral specimen or educational piece (under $10).
Certification Estimate
Gemological laboratories like GIA would issue a report identifying this as natural quartz or glass rather than diamond.
Investment Potential
None; holds no financial investment value.
Similar Diamonds
None, as this is entirely distinct from diamond in crystal system and hardness.
Setting Suggestions
Wire-wrapped pendant setting if kept as a raw mineral specimen.
Care & Maintenance
Store safely to prevent further fracturing along natural cleavage planes; clean gently with mild soap and water.
Interesting Facts
Raw quartz and glass often mimic rough diamonds to the untrained eye, but lack the extreme hardness and crystal structure of diamond.
