Not a diamond; this specimen appears to be green glass or slag material exhibiting conchoidal fracture and internal bubbles, completely distinct from crystalline diamond. - Rough/Raw broken chunk with irregular, conchoidal fracture surfaces.

Carat

Not applicable for a non-gemstone glass specimen, though visually substantial in mass.

Color

Vivid Green (Fancy Intense Green appearance, but inherent to glass composition rather than diamond coloration).

Clarity

Not applicable (contains prominent internal gas bubbles and flow lines characteristic of glass).

Shape

Rough/Raw broken chunk with irregular, conchoidal fracture surfaces.

Overall Assessment

The specimen shown in the image is definitively identified as green glass, likely cullet or slag, and is not a diamond or any other precious gemstone.

Cut Quality

Not applicable (uncut, raw industrial glass fragment).

Brilliance

Vitreous reflection typical of glass rather than the high refractive brilliance of a diamond.

Fire

Very low dispersion compared to diamond or high-index simulants.

Scintillation

Limited flash due to irregular curved surfaces rather than precision-cut facets.

Proportions

Not applicable; lacks standard facet geometry, table, depth, crown, or pavilion.

Symmetry

Asymmetrical, irregular broken shard.

Polish

Raw, unpolished fracture surfaces with vitreous luster.

Fluorescence

Unknown without UV testing, though typical green glass may show inert or weak fluorescence.

Inclusions

Internal gas bubbles, flow lines, and swirling structures typical of manufactured glass.

Blemishes

Surface chips, abrasions, and conchoidal fracture ripples.

Origin

Man-made glass / industrial slag or cullet glass.

Treatment Detection

Not applicable; the material itself is artificial glass.

Estimated Value

Nominal/decorative value only; negligible monetary value as a gemstone or industrial mineral.

Certification Estimate

Not certifiable by standard gemological grading laboratories (GIA, AGS, IGI) as a diamond.

Investment Potential

None; glass has no resale or investment value as a precious gem.

Similar Diamonds

None; diamond does not naturally occur in this form, color, or with internal glass bubbles.

Setting Suggestions

Not recommended for fine jewelry due to softness and fragility of glass.

Care & Maintenance

Handle with care to avoid chipping the soft glass edges; wash with mild soap and water.

Interesting Facts

Bright green slag or recycled glass is frequently mistaken by novices for raw precious stones like emerald or green diamond due to its striking color.
