Indeterminate Non-Diamond Material (Likely Rough Glass or Quartz)
Indeterminate Non-Diamond Material (Likely Rough Glass or Quartz) · Irregular / Rough Shard
N/A (Rough/Raw fragment) Cut
Carat
Estimated 1.5 - 2.5 carats based on visual scale
Color
Near-colorless with significant spectral dispersion
Clarity
Included (visible internal fractures and textures)
Shape
Irregular / Rough Shard
Overall Assessment
This specimen is not a diamond. The visible internal structures, fracture patterns, and light dispersion indicate a glassy or quartz-like material rather than a crystalline carbon structure.
Cut Quality
N/A (Rough/Raw fragment)
Brilliance
Low (Lacks structured facet light return)
Fire
High local dispersion (Rainbow effects seen in internal fractures)
Scintillation
Poor (Lacks patterned light/dark contrast)
Proportions
Unstructured fragment geometry; lacks standard facets
Symmetry
None (Asymmetrical fragment)
Polish
Natural/Rough texture with vitreous luster
Fluorescence
Undetermined without UV light source
Inclusions
Prominent internal flow lines, conchoidal fractures, and air bubbles
Blemishes
Surface pitting, jagged edges, and abrasions
Origin
Likely synthetic (industrial glass) or common silicate mineral
Treatment Detection
None detected; appears to be raw broken material
Estimated Value
$1 - $5 (Nominal value as a decorative fragment)
Certification Estimate
Unlikely to be graded by GIA/AGS as a diamond; would be identified as glass or mineral specimen
Investment Potential
None (No resale value in the gem market)
Similar Diamonds
None (Does not match diamond structural characteristics)
Setting Suggestions
Not suitable for traditional jewelry settings; could be used in wire wrapping
Care & Maintenance
Avoid contact with hard surfaces; material appears brittle and prone to chipping
Interesting Facts
The material shows conchoidal fracturing characteristic of glass rather than the octahedral cleavage of a diamond
