Non-diamond (Likely Cullet Glass or Slag Glass)
Non-diamond (Likely Cullet Glass or Slag Glass) · Irregular / Rough Uncut
N/A (Rough / Unfaceted) Cut
Carat
Estimated 15-25 carats based on size relative to fingers
Color
Colorless / Clear with internal rainbow dispersion
Clarity
Translucent with heavy internal swirling and flow lines
Shape
Irregular / Rough Uncut
Overall Assessment
This specimen is not a diamond. The conchoidal (shell-like) fracture patterns, internal flow lines, and lack of a crystalline structure indicate this is a piece of glass cullet or slag.
Cut Quality
N/A (Rough / Unfaceted)
Brilliance
Low; lacks the refractive index of a diamond
Fire
High internal dispersion (rainbow effect) caused by light hitting internal fractures or thickness of glass
Scintillation
Negligible
Proportions
N/A
Symmetry
None / Asymmetrical
Polish
Waxy to vitreous with conchoidal fracturing
Fluorescence
Inert / None
Inclusions
Gas bubbles, flow lines, and significant internal fracturing typical of glass
Blemishes
Conchoidal chips, surface pitting, and sharp jagged edges
Origin
Industrial waste (glass cullet) or discarded decorative glass
Treatment Detection
No professional treatments; likely a byproduct of glass manufacturing
Estimated Value
$1.00 - $5.00 (Decorative value only)
Certification Estimate
Non-certifiable as a diamond by GIA/AGS; would be identified as glass
Investment Potential
None
Similar Diamonds
None; this material does not resemble a natural or lab-grown crystal structure
Setting Suggestions
Not suitable for traditional jewelry settings; best used for craft or decorative glass projects
Care & Maintenance
Handle with care as edges appear sharp; glass is prone to scratching and shattering
Interesting Facts
Glass cullet is often mistaken for rough gemstones because of its clarity and the way it can create rainbow patterns when light hits internal stress points.
