Not applicable (raw, unprocessed fragment with conchoidal fractures) Cut
Carat
Not applicable (not a gemstone)
Color
Light blue-greenish tint
Clarity
Not applicable (contains prominent gas bubbles and internal impurities typical of glass)
Shape
Rough irregular bar / fragment
Overall Assessment
Visual inspection indicates this specimen is glass or a similar synthetic silicate rather than a genuine diamond. It lacks the crystal structure, hardness, and optical properties characteristic of diamond or other precious gemstones.
Cut Quality
Not applicable (raw, unprocessed fragment with conchoidal fractures)
Brilliance
Low to moderate, glassy luster
Fire
None
Scintillation
Poor due to lack of standard facet alignment
Proportions
Irregular elongated shard
Symmetry
Asymmetrical, irregular fragment
Polish
Raw, unpolished surface showing conchoidal ripples
Fluorescence
Unknown without UV testing
Inclusions
Large rounded gas bubbles visible internally
Blemishes
Surface chips, rough edges, and striations
Origin
Man-made glass or industrial byproduct
Treatment Detection
Not applicable
Estimated Value
Minimal/Nominal value as decorative or industrial scrap material
Certification Estimate
Gemological laboratories would not issue a diamond certificate for this material; likely identified as glass or synthetic material upon testing.
Investment Potential
None
Similar Diamonds
None (material is glass, not diamond)
Setting Suggestions
Not recommended for fine jewelry due to softness and fragile nature
Care & Maintenance
Handle with care to avoid chipping; clean with mild soapy water if used for craft purposes
Interesting Facts
The presence of rounded internal bubbles and conchoidal fracture patterns are classic indicators of glass rather than crystalline gemstone materials.
