Indeterminate - Likely Quartz or Glass based on matrix
Indeterminate - Likely Quartz or Glass based on matrix · Rough / Uncut / Irregular
Uncut (Rough) Cut

Carat
Estimated 5.0 to 15.0 carats (total visible mass)
Color
Near-colorless to Grayish (N/A for rough in this state)
Clarity
Translucent to Transparent (I-range equivalent if diamond)
Shape
Rough / Uncut / Irregular
Overall Assessment
The specimen in the image does not bear the crystalline structure or luster typical of a diamond. It most likely represents a quartz crystal or similar common silicate mineral embedded in a rocky matrix.
Cut Quality
Uncut (Rough)
Brilliance
Low (unfaceted rough material)
Fire
None visible in current state
Scintillation
None visible in current state
Proportions
N/A (Amorphous crystal form)
Symmetry
N/A (Rough stone)
Polish
N/A (Rough stone)
Fluorescence
Unknown without specialized UV light
Inclusions
Heavy veining and potential cleavage planes visible
Blemishes
Crystalline fractures and adhering host rock matrix
Origin
Likely terrestrial surface find in sedimentary or metamorphic host rock
Treatment Detection
No visible treatments; appears in natural rough state
Estimated Value
Low (Specimen value only, unless confirmed as rare mineral)
Certification Estimate
GIA Rough Diamond grading if confirmed as diamond; currently likely non-gem mineral
Investment Potential
Negligible; specimen appears to be common mineral rather than gem-quality diamond
Similar Diamonds
Rough industrial-grade bort or common quartz crystals
Setting Suggestions
Specimen display box or wire wrap if cut into a cabochon
Care & Maintenance
Do not use ultrasonic cleaners; keep in dry environment to prevent oxidation of iron-rich matrix
Interesting Facts
The crystal is embedded in a matrix that appears rich in iron oxides, typical of many metamorphic rock types.
