Simulant / Cubic Zirconia / Glass
Simulant / Cubic Zirconia / Glass · Rough / Uncut / Irregular Shard
Poor (Raw/Fragmented state) Cut
Carat
Undetermined; visual represents a fragmented segment
Color
Colorless with high dispersion (Rainbow effect)
Clarity
I3 / Included (Visible internal structural lines and surface fractures)
Shape
Rough / Uncut / Irregular Shard
Overall Assessment
This appears to be a fragmented shard of a synthetic stimulant (such as Cubic Zirconia) or glass rather than a natural gem-grade diamond, characterized by irregular fractures and high dispersion.
Cut Quality
Poor (Raw/Fragmented state)
Brilliance
Low; surface texture hinders light return
Fire
Extremely high; rainbow dispersion suggests a high refractive index simulant like CZ or Moissanite
Scintillation
Low to Moderate
Proportions
N/A (Non-geometric structure)
Symmetry
Poor / Asymmetrical
Polish
Poor (Visible striations and rough surface texture)
Fluorescence
Indeterminable from static image
Inclusions
Heavy internal fracturing, cleavage planes, and graining
Blemishes
Deep surface abrasions, jagged edges, and chips
Origin
Synthetic/Man-made simulant
Treatment Detection
N/A; likely a synthetic simulant material
Estimated Value
Minimal ($1 - $20 USD)
Certification Estimate
Unlikely to be certified by GIA/AGS in current state; may be identified by IGI as a simulant
Investment Potential
None
Similar Diamonds
Low-grade industrial bort or shattered synthetic cubic zirconia
Setting Suggestions
Not recommended for jewelry setting in current state; purely a specimen
Care & Maintenance
Avoid impact; the visible fractures indicate high fragility
Interesting Facts
The intense rainbow colors (birefringence or dispersion) are more common in high-index stimulants than in natural rough diamond
