Not a diamond; this appears to be a raw piece of optical glass or quartz crystal with conchoidal fracturing.
Not a diamond; this appears to be a raw piece of optical glass or quartz crystal with conchoidal fracturing. · Raw, uncut, and irregular crystal fragment
Uncut / Raw (Not faceted) Cut
Carat
Not applicable due to material type
Color
Colorless / Clear
Clarity
Included with numerous internal stress fractures and surface weathering
Shape
Raw, uncut, and irregular crystal fragment
Overall Assessment
The specimen shown in the image lacks the characteristic hardness, crystal habit, and optical properties of a diamond, closely resembling raw glass or quartz with distinct conchoidal fracture lines.
Cut Quality
Uncut / Raw (Not faceted)
Brilliance
Moderate vitreous luster typical of glass or quartz
Fire
Very low dispersion compared to diamond
Scintillation
Limited due to lack of precision faceting
Proportions
Irregular block fragment, non-standard proportions
Symmetry
Asymmetrical due to natural or accidental fracture patterns
Polish
Rough fracture surfaces with natural luster
Fluorescence
Unknown without UV testing
Inclusions
Heavy internal conchoidal fracture lines and stress striations
Blemishes
Surface chips, rough edges, and weathering marks
Origin
Artificial glass or common quartz mineral
Treatment Detection
None detected; likely synthetic glass or natural quartz
Estimated Value
Nominal value as a decorative mineral specimen or raw material
Certification Estimate
Not certifiable as a gemstone by major labs (GIA/AGS)
Investment Potential
Negligible investment value
Similar Diamonds
None, as this is visually identified as glass or quartz rather than diamond
Setting Suggestions
Not recommended for fine jewelry settings in its current form
Care & Maintenance
Standard handling; avoid harsh impacts to prevent further fracturing
Interesting Facts
The conchoidal fracture patterns visible resemble how brittle materials like glass and quartz break
