Non-diamond/Likely Glass Cullet or Slag - Amorphous/Rough Fragment

Carat

Estimated 20-50 carats (based on hand scale)

Color

Colorless with oily/rainbow surface interference

Amorphous/Rough Fragment

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.
