Not a diamond; this specimen appears to be industrial slag glass or raw quartz crystal showing conchoidal fracture patterns characteristic of glass rather than crystalline diamond growth. - Irregular raw chunk / rough fragment with conchoidal fractures

Carat

Not applicable as this is not a gemstone diamond; weight must be measured in grams.

Color

Colorless to slightly tinted transparent material

Clarity

Not applicable; contains numerous internal bubbles, flow lines, and fractures characteristic of glass

Shape

Irregular raw chunk / rough fragment with conchoidal fractures

Overall Assessment

This specimen is conclusively identified as glass or quartz exhibiting conchoidal fracture, not a diamond or precious gemstone.

Cut Quality

Uncut raw material with no standard faceting

Brilliance

Vitreous luster typical of glass

Fire

Very low to none, lacks the high dispersion of diamond

Scintillation

Minimal to none due to lack of standard facets

Proportions

Irregular and non-standard

Symmetry

Asymmetrical raw fragment

Polish

Unpolished natural or fractured surface

Fluorescence

Cannot be determined without UV testing

Inclusions

Gas bubbles and internal stress fractures typical of manufactured glass

Blemishes

Surface chips, rough edges, and uneven texture

Origin

Synthetic industrial byproduct or decorative glass

Treatment Detection

No enhancements, standard glass composition

Estimated Value

Minimal monetary value as decorative or industrial scrap glass

Certification Estimate

Cannot be certified as a diamond by major gemological laboratories like GIA or IGI

Investment Potential

None

Similar Diamonds

None, as this is glass rather than diamond

Setting Suggestions

Not suitable for fine jewelry settings

Care & Maintenance

Standard handling; avoid harsh impacts to prevent chipping

Interesting Facts
