Not a diamond; this is a rough green glass or slag material exhibiting conchoidal fracture and internal flow lines. - Rough, unpolished raw fragment with irregular shape

Carat

Not applicable as this is glass, but visually estimated at roughly 15-20 carats equivalent volume

Color

Deep vivid green (fancy intense green appearance, though material is glass)

Clarity

Not applicable for glass; contains numerous internal bubbles, flow lines, and debris

Shape

Rough, unpolished raw fragment with irregular shape

Overall Assessment

This specimen is a raw piece of green glass showing typical conchoidal fractures and internal bubbles, possessing no gemological relation to diamond.

Cut Quality

Not applicable (raw, uncut material)

Brilliance

Vitreous to glassy reflection, limited brilliance due to lack of standard facet proportions

Fire

Very low dispersion compared to diamond

Scintillation

Poor scintillation due to lack of precise faceting and high internal inclusion density

Proportions

Not applicable to raw unstructured material

Symmetry

Asymmetrical raw fragment

Polish

Unpolished, rough fracture surfaces with glassy luster

Fluorescence

Unknown without UV testing, typical green glass may show inert or moderate fluorescence

Inclusions

Gas bubbles, swirl marks, and internal striations characteristic of manufactured glass

Blemishes

Surface chips and conchoidal fracture marks

Origin

Man-made glass or industrial slag

Treatment Detection

Colored glass composition; no diamond treatments applicable

Estimated Value

Nominal decorative or specimen value (very low, less than $10)

Certification Estimate

Cannot be certified as a diamond; would be identified as glass by any standard gemological laboratory (GIA, IGI, etc.)

Investment Potential

None as an investment

Similar Diamonds

None, as this is visually and compositionally glass rather than diamond

Setting Suggestions

Not recommended for fine jewelry due to softness and fragile nature

Care & Maintenance

Handle with care to avoid chipping; clean with mild soapy water

Interesting Facts
