Not a diamond; appears to be raw quartz or glass slag based on the irregular elongation, conchoidal fracture, and lack of crystal faces.

Not applicable (uncut raw fragment) Cut
Carat
Estimated around 2.0 to 3.5 carats based on visible scale
Color
Colorless with slight grey/greenish tint
Clarity
Included / Heavily flawed due to internal fractures and debris
Shape
Uncut raw crystal fragment / Irregular elongated shard
Overall Assessment
The specimen shown is an irregular transparent crystal or glass shard rather than a diamond, featuring prominent surface irregularities and fractures.
Cut Quality
Not applicable (uncut raw fragment)
Brilliance
Poor, lacks standard gemstone optical properties due to raw state
Fire
Minimal to none
Scintillation
None
Proportions
Not applicable to raw rough material
Symmetry
Asymmetrical raw fragment
Polish
None (natural or fractured surface)
Fluorescence
Cannot be determined without UV testing, likely None
Inclusions
Heavy internal fracturing, particulate inclusions, and adhering matrix material
Blemishes
Surface scratches, chips, and irregular fracture planes
Origin
Natural mineral rough or industrial byproduct
Treatment Detection
No obvious treatments, but material requires formal physical/chemical testing
Estimated Value
Nominal value as a mineral specimen or glass piece (under $10)
Certification Estimate
Standard gemological laboratories (GIA, IGI) would not certify this as a gemstone; would require preliminary testing to confirm material identity.
Investment Potential
Negligible
Similar Diamonds
None (this specimen is not a diamond)
Setting Suggestions
Wire-wrapped raw mineral setting if desired for decorative purposes
Care & Maintenance
Store carefully to prevent chipping of fragile edges; wash gently with warm soapy water if needed
Interesting Facts
Many untrained individuals mistake quartz crystals or glass shards for rough diamonds due to their transparent appearance.
