Not a diamond; likely manufactured glass, quartz fragment, or ice due to the presence of rounded air bubbles, conchoidal fractures, and non-crystalline surface texture.
Not a diamond; likely manufactured glass, quartz fragment, or ice due to the presence of rounded air bubbles, conchoidal fractures, and non-crystalline surface texture. · Irregular raw fragment / unstructured shard
Not applicable (uncut or crudely fractured piece) Cut
Carat
Not applicable for non-diamond material
Color
Colorless / Transparent with surface reflections
Clarity
Not applicable (contains obvious gas bubbles and internal impurities typical of glass)
Shape
Irregular raw fragment / unstructured shard
Overall Assessment
The specimen displayed in the image is definitively not a diamond. Visual indicators such as rounded gas bubbles and non-gem quality fracture patterns confirm it is likely a piece of manufactured glass or debris rather than crystalline carbon.
Cut Quality
Not applicable (uncut or crudely fractured piece)
Brilliance
Low to moderate vitreous luster, lacking true diamond dispersion
Fire
Minimal to none; lacks the high refractive index and dispersion of a genuine diamond
Scintillation
Poor, lacking precise facet arrangements required for optimal light return
Proportions
Non-standard, irregular fragment geometry
Symmetry
Asymmetrical / Irregular
Polish
Crude, uneven, showing conchoidal fracture patterns
Fluorescence
Unknown without UV testing
Inclusions
Prominent spherical gas bubbles, swirl marks, and internal stress fractures
Blemishes
Rough edges, chips, and surface striations
Origin
Man-made glass or natural quartz/mineral shard
Treatment Detection
N/A
Estimated Value
Minimal monetary value as it is not a precious gemstone
Certification Estimate
Cannot be certified as a diamond by standard gemological laboratories (GIA, AGS, IGI)
Investment Potential
None
Similar Diamonds
None
Setting Suggestions
Not recommended for jewelry setting due to material fragility
Care & Maintenance
Handle with care to avoid cuts from sharp edges if glass
Interesting Facts
Many untrained individuals mistake discarded glass fragments with conchoidal fractures for raw diamonds due to their transparent appearance.
