Not a diamond (likely quartz, glass, or industrial crystal based on the conchoidal fractures, internal gas bubbles, and amorphous structure visible)
Not a diamond (likely quartz, glass, or industrial crystal based on the conchoidal fractures, internal gas bubbles, and amorphous structure visible) · Rough / Raw irregular fragment
Not applicable (uncut raw specimen) Cut

Carat
Cannot be accurately determined by visual assessment alone, roughly estimated > 10 carats based on physical size
Color
Colorless to light brownish tint
Clarity
Included / Heavily flawed (I3 equivalent due to numerous internal fractures and inclusions)
Shape
Rough / Raw irregular fragment
Overall Assessment
Based on a visual inspection of the surface characteristics, fracture patterns, and internal structure, this specimen is definitively not a diamond. Further physical and chemical testing (such as a thermal conductivity probe or refractometer) is recommended to correctly identify the material.
Cut Quality
Not applicable (uncut raw specimen)
Brilliance
Poor due to lack of standard facet alignment and internal fracturing
Fire
Minimal to none due to material properties and lack of dispersion
Scintillation
Absent due to lack of facet pattern and cutting
Proportions
Not applicable to raw rough material
Symmetry
Not applicable (raw, uncut specimen)
Polish
Unpolished natural/raw surface with visible conchoidal fracture textures
Fluorescence
Unknown without UV testing
Inclusions
Multiple internal fractures, particulate inclusions, and possible gas bubbles indicating non-diamond material
Blemishes
Surface conchoidal fractures, abrasions, and irregular texture
Origin
Natural mineral or synthetic glass fragment
Treatment Detection
No standard gemstone treatments detected, but material authenticity is highly questionable
Estimated Value
Minimal (low monetary value as it is not a genuine diamond)
Certification Estimate
Not eligible for GIA, AGS, or standard diamond grading laboratories; would require standard gemological testing to identify the actual mineral
Investment Potential
None as an investment asset
Similar Diamonds
None (this specimen does not share optical or physical properties with gem-grade diamonds)
Setting Suggestions
Wire-wrapping or bespoke artisan setting if used as a mineral specimen, but not recommended for fine jewelry
Care & Maintenance
Standard gentle cleaning with warm soapy water and a soft brush; avoid harsh impacts due to internal fractures
Interesting Facts
The visible conchoidal fracture patterns and potential internal bubbles strongly suggest this is quartz or glass rather than carbon-based diamond
