Not a diamond; this specimen appears to be rough quartz or mineral glass with conchoidal fracturing.
Not a diamond; this specimen appears to be rough quartz or mineral glass with conchoidal fracturing. · Rough / Raw Uncut Crystal
Not applicable (rough mineral specimen without standard facet cuts). Cut
Carat
Cannot be determined accurately by visual assessment alone, estimated to be substantial in total weight.
Color
Colorless with minor surface inclusions and soil staining.
Clarity
Included due to internal fractures, fissures, and inclusions.
Shape
Rough / Raw Uncut Crystal
Overall Assessment
This specimen is a naturally occurring rough mineral (likely quartz) displaying distinct conchoidal fractures rather than a diamond.
Cut Quality
Not applicable (rough mineral specimen without standard facet cuts).
Brilliance
Low to moderate vitreous luster, depending on light angle.
Fire
Very low dispersion compared to diamond.
Scintillation
Minimal due to lack of standard faceting.
Proportions
Not applicable for rough stones.
Symmetry
Asymmetrical, natural rough form.
Polish
Raw, unpolished natural surface with conchoidal fracture textures.
Fluorescence
Unknown without UV testing.
Inclusions
Visible internal fractures, fissures, and possible mineral inclusions.
Blemishes
Surface scratches, pitting, and soil/dirt residue.
Origin
Natural terrestrial mineral specimen.
Treatment Detection
No obvious treatments detected, appears completely natural.
Estimated Value
Nominal value as a mineral specimen or rough quartz piece.
Certification Estimate
Standard gemological laboratories (GIA, IGI) would not certify this as a diamond; it requires basic identification testing (refractive index, polariscope).
Investment Potential
Low investment potential; valued primarily for decorative or collection purposes.
Similar Diamonds
None, as this is not a diamond.
Setting Suggestions
Wire-wrapped rough stone jewelry or displayed as a mineral specimen.
Care & Maintenance
Clean gently with warm soapy water and a soft brush; avoid harsh chemicals and impact.
Interesting Facts
The smooth, curved surfaces showing concentric ripples are known as conchoidal fractures, typical of brittle materials like quartz or glass.
