Natural Rough Crystal (Likely Quartz or similar mineral)
Natural Rough Crystal (Likely Quartz or similar mineral) · Natural Rough / Uncut
N/A (Rough State) Cut
Carat
Estimated 15-25 carats based on finger scale
Color
Near Colorless with faint yellow/brown tinting
Clarity
I2 to I3 (Included)
Shape
Natural Rough / Uncut
Overall Assessment
The specimen lacks the high refractive index and characteristic octahedral growth usually associated with high-quality diamond rough; it more closely resembles a silicate mineral like Quartz or Topaz.
Cut Quality
N/A (Rough State)
Brilliance
Low (typical of unpolished rough)
Fire
Low (high dispersion not visible in rough state)
Scintillation
Low (requires facets for light interplay)
Proportions
Elongated, tabular rough growth with conchoidal fracturing
Symmetry
N/A (Natural Growth)
Polish
N/A (Raw Surface)
Fluorescence
Cannot be determined without UV light
Inclusions
Dark pinpoint crystals, internal fractures, and iron staining
Blemishes
Heavy surface pitting and step-like growth features
Origin
Alluvial deposit or pegmatite source
Treatment Detection
None visible; appears to be raw earth-mined state
Estimated Value
Low as a diamond specimen ($50-$200) due to clarity; negligible if common quartz
Certification Estimate
GIA (Rough Diamond Report) if confirmed as diamond
Investment Potential
Low; lacks gem-quality clarity for faceted investment
Similar Diamonds
Low-grade industrial rough or macle crystals
Setting Suggestions
Wire-wrapped pendant or custom 'rough cut' claw setting
Care & Maintenance
Avoid ultrasonic cleaners if fractures reach the surface; clean with soft brush and warm water
Interesting Facts
The flat, step-like growth lines on the side are characteristic of trigons or parallel growth in crystals
