Natural Rough Crystal (Likely Quartz or Glass)
Natural Rough Crystal (Likely Quartz or Glass) · Rough/Uncut
Uncut / Raw State Cut
Carat
Estimated 15-25 carats based on finger scale
Color
Near Colorless to Faint Gray
Clarity
Included/I3 (Industrial Grade if Diamond)
Shape
Rough/Uncut
Overall Assessment
This is a raw mineral specimen. While it has some diamond-like features, the conchoidal fracture pattern and massive internal cleaving suggest it is more likely a silicate mineral like Quartz or a piece of glass than a gem-quality diamond.
Cut Quality

None - Rough Crystal
Polish
Natural Growth Striations/Fracture Surfaces

Cannot determine without UV light
Inclusions
Heavy internal fractures, cleavage planes, and step-like grow figures

Conchoidal fractures and impact nicks
Origin
Likely alluvial source or silicate mineral find
Treatment Detection
No obvious treatments; appears to be raw mineral
Estimated Value
$10 - $50 (If Quartz/Glass); higher if confirmed as diamond rough
Certification Estimate
GIA (Rough Diamond Report) if diamond, otherwise GIA Gem Identification Report
Investment Potential
Low (Speculative unless confirmed as diamond)
Similar Diamonds
Uncut industrial-grade bort or rough quartz crystal
Setting Suggestions
Wire wrap or custom rough-stone jewelry
Care & Maintenance
Avoid high heat or ultrasonic cleaning due to internal fractures
Interesting Facts
The step-like growth lines on the surface are characteristic of natural minerals, though the fracture pattern looks similar to silica glass or quartz.
