Not a diamond; this specimen appears to be green glass or slag, possibly colored with chromium or copper, exhibiting conchoidal fracture patterns. - Raw, unpolished, irregular fragment with natural or broken conchoidal surfaces

Carat

Cannot be precisely determined without volume and density measurements, but visually estimated at roughly 10-15 carats equivalent volume.

Color

Vivid Fancy Green (Saturation is high, likely artificial or non-gem mineral origin)

Clarity

Included (shows numerous internal bubbles, flow lines, and stress fractures typical of glass)

Shape

Raw, unpolished, irregular fragment with natural or broken conchoidal surfaces

Overall Assessment

This specimen is a vibrant green rough fragment, most likely glass or slag, rather than a genuine diamond or precious gemstone. Its internal bubble structures and fracture patterns clearly distinguish it from natural crystalline minerals.

Cut Quality

Not applicable (uncut raw fragment)

Brilliance

Low to moderate vitreous luster, lacks true diamond dispersion and internal reflection

Fire

Minimal to none; lacks the high refractive index and dispersion of a diamond

Scintillation

Poor, due to lack of facet geometry and presence of internal diffusion

Proportions

N/A - Irregular rough fragment

Symmetry

Asymmetrical due to random fracture and breakage

Polish

None (rough surface texture)

Fluorescence

Unknown without UV testing, though some green glasses exhibit inert or weak fluorescence.

Inclusions

Gas bubbles, swirl marks, and internal linear stress fractures characteristic of manufactured glass

Blemishes

Surface chips, rough edges, and uneven texture

Origin

Man-made glass / industrial or decorative cullet

Treatment Detection

Colored glass composition with visible internal melt/flow features

Estimated Value

Minimal (novelty or ornamental value only, typically under $5)

Certification Estimate

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

Investment Potential

None as a gemstone or investment asset

Similar Diamonds

None, as this is visually and compositionally not a diamond

Setting Suggestions

Wire-wrapping or bezel setting if used for craft or costume jewelry purposes

Care & Maintenance

Standard cleaning with mild soap and warm water; avoid harsh impacts as glass is brittle

Interesting Facts

Green glass is frequently mistaken for rough emerald, green tourmaline, or colored diamond by untrained observers due to its striking color and vitreous appearance.
