Not a diamond; appears to be raw quartz, glass, or quartz crystal with conchoidal fractures
Not a diamond; appears to be raw quartz, glass, or quartz crystal with conchoidal fractures · Raw, uncut, amorphous rough mineral specimen
Poor (Uncut raw specimen with no standard faceting) Cut
Carat
Cannot be accurately determined by visual estimation alone without precise density and volume measurements, roughly estimated at over 10 carats equivalent weight in mineral mass
Color
Colorless to slightly tinted with surface iridescence
Clarity
Included / heavily fractured (Not applicable to gem-grade diamonds)
Shape
Raw, uncut, amorphous rough mineral specimen
Overall Assessment
This specimen is visually identified as non-diamond rough material, likely quartz or glass, displaying distinct conchoidal fracture planes rather than crystal cleavage or diamond facets.
Cut Quality
Poor (Uncut raw specimen with no standard faceting)
Brilliance
Low due to lack of standard gemstone faceting and internal fractures
Fire
Minimal dispersion, mostly localized rainbow iridescence from surface micro-fractures
Scintillation
Very poor due to lack of symmetry and standard pavilion/crown facets
Proportions
Irregular proportions due to natural or broken rough state
Symmetry
Asymmetrical raw formation
Polish
Unpolished natural or fractured surface showing conchoidal fracture patterns
Fluorescence
Unknown without UV testing, though some surface coatings or inclusions may show mild reaction
Inclusions
Extensive internal fracturing, feather-like inclusions, and potential gas bubbles if glass
Blemishes
Surface chips, natural irregularities, and conchoidal break lines
Origin
Natural mineral rough or manufactured glass cullet
Treatment Detection
Possible surface coating or heat stress fractures visible
Estimated Value
Nominal decorative or mineral specimen value (very low commercial value compared to gemstones)
Certification Estimate
Not eligible for standard diamond grading reports (GIA, AGS, IGI) as it is not a diamond
Investment Potential
None as an investment; purely a decorative or geological specimen
Similar Diamonds
None, as this material lacks diamond properties entirely
Setting Suggestions
Wire-wrapped rough mineral setting or decorative display piece
Care & Maintenance
Handle with care to prevent further chipping along existing fracture lines; clean with mild soapy water
Interesting Facts
Displays prominent conchoidal fractures which are characteristic of brittle materials like glass and quartz when broken
