Not a diamond; this is a piece of green glass containing prominent gas bubbles and flow lines, indicative of manufactured or processed glass rather than a crystalline gemstone.
Not a diamond; this is a piece of green glass containing prominent gas bubbles and flow lines, indicative of manufactured or processed glass rather than a crystalline gemstone. · Irregular raw or broken shard, unpolished and uncut.
Not applicable (uncut raw shard). Cut
Carat
Not applicable as this is glass, but visually appears to be a large fragment weighing several grams.
Color
Olive green or brownish-green.
Clarity
Included heavily with gas bubbles, swirls, and flow structures.
Shape
Irregular raw or broken shard, unpolished and uncut.
Overall Assessment
The specimen is definitively identified as green glass, easily distinguished by internal gas bubbles and conchoidal fractures, possessing no gemological relation to diamond.
Cut Quality
Not applicable (uncut raw shard).
Brilliance
Low to moderate vitreous luster, lacking true diamond-like optical performance.
Fire
None, as dispersion is virtually non-existent in glass compared to diamond.
Scintillation
Poor, due to lack of standard facet patterns.
Proportions
Not applicable.
Symmetry
Not applicable (asymmetrical fragment).
Polish
Rough, fractured surface with visible conchoidal fracture patterns.
Fluorescence
Indeterminate without UV testing, though typical green glass may show weak fluorescence depending on additives.
Inclusions
Numerous spherical and elongated gas bubbles, swirl marks, and flow lines visible throughout the matrix.
Blemishes
Surface scratches, chipped edges, and uneven fractures from breakage.
Origin
Man-made glass, potentially industrial, decorative, or recycled bottle glass.
Treatment Detection
No gemstone treatments; purely synthetic vitreous material.
Estimated Value
Nominal or decorative value only; virtually zero commercial gemstone value.
Certification Estimate
Not certifiable as a gemstone by major gemological laboratories (GIA, IGI, etc.); would be identified as glass.
Investment Potential
None.
Similar Diamonds
None, as diamond is a crystalline mineral composed of pure carbon, whereas this is amorphous silicon dioxide (glass).
Setting Suggestions
Not recommended for jewelry settings due to low durability and softness compared to gemstones.
Care & Maintenance
Handle with care to avoid cuts from sharp edges; clean with mild soap and water.
Interesting Facts
The presence of rounded gas bubbles is a definitive diagnostic feature distinguishing manufactured glass from natural green gemstones like emerald, peridot, or green diamond.
