Overall Assessment
This specimen is not a diamond. It is an amorphous piece of glass or industrial material, identified by its distinct shell-like fracture patterns and lack of crystalline structure.
Cut Quality
Uncut/Rough
Brilliance
Low (vitreous luster)
Fire
Surface thin-film interference (not internal dispersion)
Scintillation
None
Proportions
Irregular
Symmetry
None (irregular fragment)
Polish
N/A (natural fracture surfaces)
Fluorescence
Likely none (inert)
Inclusions
Conchoidal fracture lines and workflow ridges
Blemishes
Heavy surface scratching and impact marks
Origin
Industrial byproduct or glass manufacturing waste
Treatment Detection
None
Estimated Value
Negligible market value
Certification Estimate
Ineligible for diamond grading
Investment Potential
Low to none
Similar Diamonds
None (material is non-adamantine)
Setting Suggestions
Specimen display container only
Care & Maintenance
Handle with care as the sharp conchoidal edges can be dangerous
Interesting Facts
The scalloped edges shown are classic conchoidal fractures, diagnostic of glass or quartz rather than diamond.
