Not a diamond; this specimen exhibits conchoidal fractures, curved surface striations, and internal bubbles characteristic of manufactured glass or slag, rather than crystalline diamond structure.
Not a diamond; this specimen exhibits conchoidal fractures, curved surface striations, and internal bubbles characteristic of manufactured glass or slag, rather than crystalline diamond structure. · Irregular fragment with curved, conchoidal fracture patterns.
Not applicable (raw fractured glass, unpolished) Cut
Carat
Not applicable for gem-grade evaluation; weight in carats is meaningless for glass debris.
Color
Colorless / Clear
Clarity
Included due to visible interior bubbles and flow lines
Shape
Irregular fragment with curved, conchoidal fracture patterns.
Overall Assessment
The specimen shown in the image is definitively identified as a piece of broken glass, easily distinguished from a true diamond by the presence of internal air bubbles, curved conchoidal ripple marks, and lack of crystalline structure.
Cut Quality
Not applicable (raw fractured glass, unpolished)
Brilliance
Vitreous luster, low light return compared to high-index gems
Fire
Minimal dispersion, far lower fire than diamond or moissanite
Scintillation
Poor light performance due to random fractured surfaces
Proportions
Not applicable (no standard pavilion, crown, or table proportions)
Symmetry
Asymmetrical, completely lacking standard gem faceting symmetry
Polish
Unpolished, rough fracture surfaces with natural vitreous luster
Fluorescence
Indeterminate without UV testing
Inclusions
Distinct spherical gas bubbles visible inside the material, typical of glass production
Blemishes
Surface chips, sharp edges, and conchoidal ripple marks
Origin
Man-made industrial glass or discarded bottle/container fragment
Treatment Detection
No gemstone treatments applied; purely manufactured material
Estimated Value
Nominal / Zero monetary value as a gemstone (scrap material)
Certification Estimate
Cannot be certified by major gemological labs like GIA or AGS as a gemstone; would be identified as synthetic glass upon testing.
Investment Potential
None; holds no investment or resale value
Similar Diamonds
None; this material shares no physical or optical properties with diamond
Setting Suggestions
Not recommended for jewelry settings due to softness, fragility, and lack of gemological value
Care & Maintenance
Handle carefully with protective gloves to avoid cuts from sharp, fractured edges
Interesting Facts
Glass often mimics rough crystals to the untrained eye due to its transparency and conchoidal fracture, which superficially resembles the cleavage or fracture planes of certain minerals.
