Not a diamond; appears to be quartz, glass, or another transparent crystalline mineral / raw crystal fragment.
Not a diamond; appears to be quartz, glass, or another transparent crystalline mineral / raw crystal fragment. · Raw, uncut, or irregularly fractured crystalline fragment.
Not applicable (unfaceted raw stone). Cut

Carat
Not applicable / uncalibrated raw mineral chunk (visual estimate is misleading due to high impurities and irregular shape).
Color
Colorless to light smoky grey with inclusions.
Clarity
I3 (Heavy inclusions, internal fractures, and structural flaws visible).
Shape
Raw, uncut, or irregularly fractured crystalline fragment.
Overall Assessment
The specimen shown in the image is definitively not a diamond. It exhibits characteristic conchoidal fractures, irregular surface structures, and internal veining typical of raw quartz, glass, or another common translucent silicate mineral rather than crystallized diamond rough.
Cut Quality
Not applicable (unfaceted raw stone).
Brilliance
Low to moderate vitreous luster, limited by internal fractures and lack of precise faceting.
Fire
Minimal dispersion, typical of quartz or glass rather than high-dispersion gemstones.
Scintillation
Poor sparkle due to lack of standard symmetrical facet arrangements.
Proportions
Non-standard; un-cut rough mineral specimen.
Symmetry
Poor / Asymmetrical due to natural raw formation and fracture lines.
Polish
Raw, unpolished surface showing conchoidal fracturing and natural crystal faces.
Fluorescence
Indeterminate from visual assessment alone.
Inclusions
Prominent internal feather fractures, veil inclusions, and cloudy zones.
Blemishes
Surface scratches, natural chipping, and conchoidal fracture marks.
Origin
Natural geological mineral formation (likely quartz or similar silicate).
Treatment Detection
No obvious signs of human treatment; appears in a natural rough state.
Estimated Value
Nominal / decorative specimen value only (low economic value as it is not a precious diamond).
Certification Estimate
Not eligible for GIA or major diamond grading reports (would require standard gemological testing for mineral identification).
Investment Potential
None as an investment asset; strictly a mineral specimen or craft material.
Similar Diamonds
None, as this specimen is not a diamond.
Setting Suggestions
Wire-wrapped organic setting or raw mineral bezel if used in artisanal jewelry.
Care & Maintenance
Avoid harsh impacts to prevent further fracturing along existing feather cleavage planes; clean gently with mild soapy water.
Interesting Facts
The conchoidal fracture patterns visible on the surface strongly resemble glass or quartz rather than the octahedral cleavage typical of rough diamonds.
