Not a diamond; appears to be industrial silicon, glass, or a synthetic metallic crystal fragment with conchoidal fracture and metallic luster.
Not a diamond; appears to be industrial silicon, glass, or a synthetic metallic crystal fragment with conchoidal fracture and metallic luster. · Irregular / Raw Crystalline Fragment
Not applicable (uncut raw or fractured material) Cut
Carat
Not applicable due to non-diamond material and irregular fragment shape.
Color
Metallic dark gray / iridescent sheen
Clarity
Not applicable; opaque with internal stress fractures and striations.
Shape
Irregular / Raw Crystalline Fragment
Overall Assessment
The visual evidence indicates this is an industrial or synthetic fragment (likely silicon or a metallic compound) showing classic conchoidal fracture patterns, not a diamond or gemstone.
Cut Quality
Not applicable (uncut raw or fractured material)
Brilliance
Metallic luster with specular reflection, but lacks optical diamond brilliance
Fire
None; lacks the high dispersion of a gemstone
Scintillation
Reflective flash effect due to metallic or glassy cleavage planes rather than facet patterns
Proportions
Irregular blocky fragment with conchoidal fracture steps
Symmetry
Asymmetrical raw fracture
Polish
Raw fractured surface, no gem polish
Fluorescence
None observed
Inclusions
Dense internal stress lines, parallel striations, and micro-fractures
Blemishes
Chipped edges, natural fracture planes, and uneven surface texture
Origin
Industrial manufacturing byproduct (e.g., polycrystalline silicon or synthetic metallic scrap)
Treatment Detection
No standard gemstone treatments; raw industrial material
Estimated Value
Minimal scrap or industrial material value; negligible gem value
Certification Estimate
Not certifiable by gemological labs (GIA/AGS/IGI); requires material science analysis (e.g., XRD or XRF)
Investment Potential
None as a gemstone or precious asset
Similar Diamonds
None; physically and chemically unrelated to diamond
Setting Suggestions
Not recommended for jewelry settings due to material properties
Care & Maintenance
Handle with care to avoid sharp edges; store dry
Interesting Facts
Displays striking conchoidal fractures and fibrous cleavage patterns resembling high-purity silicon or metallic slag.
