Not a diamond (appears to be raw quartz, glass, or industrial slag)
Not a diamond (appears to be raw quartz, glass, or industrial slag) · Raw, unpolished crystal / rough fragment
Not applicable (uncut raw material) Cut
Carat
Roughly 15 to 25 carats (estimated by visual bulk)
Color
Colorless / Transparent
Clarity
Included / Heavily fractured
Shape
Raw, unpolished crystal / rough fragment
Overall Assessment
This specimen is definitively not a diamond. Based on surface striations, texture, and lack of diamond crystal habit, it is likely a piece of raw quartz or industrial glass. It holds no gemstone or monetary value.
Cut Quality
Not applicable (uncut raw material)
Brilliance
Low to moderate due to internal fracturing and lack of facet alignment
Fire
Minimal dispersion observed in this raw state
Scintillation
Poor, lacking the precise geometry required for faceted sparkle
Proportions
Irregular raw specimen with no standard table or pavilion measurements
Symmetry
Asymmetrical raw formation
Polish
Raw unpolished surface with natural striations and fracture lines
Fluorescence
Unknown / Not tested
Inclusions
Numerous internal fractures, feather inclusions, and particulate matter
Blemishes
Surface chips, rough patches, and striations characteristic of unprocessed material
Origin
Natural mineral or manufactured glass slag (cannot be precisely determined without chemical testing)
Treatment Detection
None apparent, though industrial processing marks may be present
Estimated Value
Nominal value as a mineral specimen (less than $10)
Certification Estimate
Not eligible for standard gemstone certification by major labs like GIA or AGS
Investment Potential
None
Similar Diamonds
None (this is not a diamond)
Setting Suggestions
Not recommended for fine jewelry due to softness/fragility; could be used in wire-wrapping or mineral display
Care & Maintenance
Handle with care to prevent further chipping along internal fracture planes; clean with mild soap and water
Interesting Facts
Many untrained individuals mistake raw quartz crystals or glass slag for rough diamonds due to their transparent appearance and vitreous luster
