Not applicable (Raw, uncut, and unpolished) Cut
Carat
Not applicable (Not a diamond)
Color
Colorless / Clear with surface dirt and inclusions
Clarity
Not applicable (Contains heavy internal fracturing and debris)
Shape
Rough / Irregular, un-faceted amorphous chunk
Overall Assessment
The specimen displayed in the image is definitively not a diamond. It shows characteristic conchoidal fracture patterns and surface textures typical of glass, slag, or quartz, and holds no gemological or diamond market value.
Cut Quality
Not applicable (Raw, uncut, and unpolished)
Brilliance
Low to moderate vitreous luster, limited by lack of proper facets
Fire
Minimal to none
Scintillation
Poor, lacks facet structure to return light dynamically
Proportions
Not applicable
Symmetry
Asymmetrical
Polish
None (Rough fracture surfaces)
Fluorescence
Unknown / Not tested
Inclusions
Extensive internal fracturing, conchoidal ripples, and trapped particulate matter/dirt
Blemishes
Rough edges, chips, and surface irregularities from breakage
Origin
Man-made glass or industrial slag, non-gem material
Treatment Detection
None applicable
Estimated Value
Minimal / Nominal decorative or collector value as a mineral/glass specimen
Certification Estimate
Cannot be graded by major diamond laboratories (GIA, AGS, IGI) as it is not a diamond or gemstone.
Investment Potential
None
Similar Diamonds
None, as this material is entirely unrelated to diamond.
Setting Suggestions
Not suitable for fine jewelry settings due to low hardness and fragility
Care & Maintenance
Handle with care to avoid cuts from sharp edges; clean with mild soap and water if needed.
Interesting Facts
The visible curved ripple marks are known as conchoidal fractures, which typically form when brittle materials like glass or quartz break.
