Non-Diamond (Likely Glass or Quartz)
Non-Diamond (Likely Glass or Quartz) · Rough / Uncut (Irregular Fragment)
N/A (Uncut/Rough) Cut
Carat
Estimated 10-20 carats (based on scale)
Color
Near Colorless / Translucent
Clarity
Included (I3 or lower equivalent)
Shape
Rough / Uncut (Irregular Fragment)
Overall Assessment
This specimen is not a diamond. The conchoidal (shell-like) fracture patterns and the lack of characteristic crystal symmetry indicate this is a piece of amorphous glass or a common mineral like quartz.
Cut Quality
N/A (Uncut/Rough)
Brilliance
Low; light passes through without concentrated reflection.
Fire
Moderate (Visible rainbow prismatic effect caused by internal fractures, not dispersion).
Scintillation
Low to None.
Proportions
N/A
Symmetry
N/A
Polish
N/A (Natural/Fracture surface)
Fluorescence
Cannot determine without UV light
Inclusions
Heavy internal fractures, veining, and structural irregularities consistent with glass or low-grade mineral.
Blemishes
Conchoidal fractures, sharp jagged edges, and surface abrasions.
Origin
Likely industrial glass or common silicate mineral.
Treatment Detection
No visible gemological treatments; natural breakage patterns present.
Estimated Value
$1 - $10 (Decorative/Educational value only)
Certification Estimate
Unlikely to be certified by major labs like GIA as a diamond.
Investment Potential
None.
Similar Diamonds
None; this does not share the physical properties of diamond.
Setting Suggestions
Not suitable for jewelry setting due to fragility and low value.
Care & Maintenance
Handle with care as edges appear sharp; clean with mild soap and water.
Interesting Facts
The rainbow colors seen are caused by 'thin-film interference' or light diffraction within internal fractures, a common sight in broken glass or quartz.
