The provided image displays a material likely to be industrial glass or slag, not a diamond. It lacks the crystal structure of natural or lab-grown diamonds. - Rough, irregular, and glassy fragment. It does not have a formal jewelry cut.

Carat

Estimated at 5 to 10 carats based on visual size comparison with fingertips.

Color

Deep forest green to blue-green (Not applicable to white diamond D-Z scale).

Clarity

Heavily included/opaque due to surface wear and internal bubble-like features.

Shape

Rough, irregular, and glassy fragment. It does not have a formal jewelry cut.

Overall Assessment

The specimen is not a diamond. Based on the deep green color, surface texture, and fracture patterns, it appears to be a fragment of green industrial glass or 'sea glass' that has undergone significant environmental weathering.

Cut Quality

None (Rough material/Raw fragment).

Brilliance

Very Low; minimal internal light return.

Fire

None; lacks the refractive index required for spectral dispersion.

Scintillation

None; surface is too matte and irregular for sparkle.

Proportions

N/A.

Symmetry

N/A (Irregular shape).

Polish

Very Poor; showing signs of conchoidal (glass-like) fracturing and heavy surface abrasion.

Fluorescence

None observed visually.

Inclusions

Large internal swirls and potential air bubbles indicative of glass, not diamond.

Blemishes

Severe surface scratching, pitting, and conchoidal chips on the edges.

Origin

Man-made industrial byproduct or discarded container glass (sea glass).

Treatment Detection

N/A (Non-diamond material).

Estimated Value

Minimal to zero market value as a gemstone; primarily of curiosity or decorative value.

Certification Estimate

Unlikely to be accepted by GIA or IGI as a diamond; would likely be identified as glass or synthetic spinal/glass slag.

Investment Potential

None.

Similar Diamonds

None; this material does not resemble natural green diamonds (which are typically much lighter and more translucent).

Setting Suggestions

Not recommended for fine jewelry settings; possibly suitable for wire wrapping as a curios item.

Care & Maintenance

Avoid impact as glass is brittle; clean with warm soapy water.

Interesting Facts

The curved, shell-like (conchoidal) fracture markings are a classic diagnostic feature used to distinguish glass from crystalline gemstones like diamonds.
