Not a diamond; appears to be quartz, glass, or a synthetic imitation material showing conchoidal fracture patterns.
Not a diamond; appears to be quartz, glass, or a synthetic imitation material showing conchoidal fracture patterns. · Irregular / Raw fragment or cut piece with heavily fractured internal structure
Poor / Unconventional rough or broken shard Cut
Carat
Difficult to estimate accurately from visual angle, roughly 2.0 to 4.0 carats equivalent volume
Color
Colorless / Near-colorless
Clarity
I3 (Extremely heavily included/fractured)
Shape
Irregular / Raw fragment or cut piece with heavily fractured internal structure
Overall Assessment
This item is definitively not a diamond. It displays prominent conchoidal fractures and internal stress patterns characteristic of quartz, glass, or another brittle crystalline mineral subjected to thermal stress or impact.
Cut Quality
Poor / Unconventional rough or broken shard
Brilliance
Very low due to extensive internal scattering and fracturing
Fire
Minimal to none
Scintillation
Poor, light is scattered internally rather than reflected uniformly
Proportions
Non-standard, highly irregular dimensions
Symmetry
Poor / Asymmetrical
Polish
Fair to Poor, showing rough surface textures and conchoidal fractures
Fluorescence
Cannot be determined without UV testing
Inclusions
Massive internal fracturing, feather fractures, tension cracks, and structural inclusions throughout
Blemishes
Surface scratches, chips, and irregular fracture breakouts
Origin
Unknown mineral or synthetic glass fragment
Treatment Detection
Possible stress fracturing, thermal shock, or intentional heat-fracturing (often seen in 'ice quartz' or treated quartz)
Estimated Value
Nominal / Low decorative or mineral specimen value (less than $50 USD)
Certification Estimate
Major laboratories like GIA or IGI would not issue diamond grading reports for this material as it is not diamond.
Investment Potential
None; holds no investment or resale value as a gemstone
Similar Diamonds
None, as this material lacks diamond physical and optical properties
Setting Suggestions
Wire-wrap or protective bezel setting if used in artisan jewelry, due to extreme fragility
Care & Maintenance
Handle with extreme care; highly susceptible to breaking further along existing internal fracture planes
Interesting Facts
The internal fractured appearance resembles 'ice quartz' or quenched glass where thermal shock creates a web of internal fractures.
