Non-Gemstone (Likely Glass or Quartz)
Non-Gemstone (Likely Glass or Quartz) · Rough / Uncut fragment
Uncut Cut
Carat
Estimated 10-20 carats (based on hand scale)
Color
Colorless to Near-Colorless
Clarity
Included / Transparent with internal fractures
Shape
Rough / Uncut fragment
Overall Assessment
This specimen is not a diamond. Based on the fracture patterns, transparency, and lack of characteristic diamond lustre, it is most likely a shard of glass or a piece of rough quartz.
Cut Quality
Uncut
Brilliance
Low (typical of low refractive index materials)
Fire
None visible
Scintillation
Minimal
Proportions
Irregular
Symmetry
None (Irregular fragment)
Polish
N/A (Rough surface)
Fluorescence
Inconclusive without UV light
Inclusions
Conchoidal fractures and internal stress lines typical of glass or silica
Blemishes
Chipped edges and impact marks
Origin
Likely anthropogenic (Glass) or common mineral (Quartz)
Treatment Detection
None applicable
Estimated Value
Negligible market value
Certification Estimate
Not eligible for diamond grading (likely identified as Glass or Quartz by GIA/IGI)
Investment Potential
None
Similar Diamonds
None; characteristics do not match diamond
Setting Suggestions
Not recommended for jewelry setting due to low hardness/durability
Care & Maintenance
Avoid impact and thermal shock
Interesting Facts
The shell-like (conchoidal) fractures seen here are characteristic of amorphous materials like glass, whereas diamonds have octahedral cleavage.
