Likely Quartz or Cubic Zirconia (Simulant)
Likely Quartz or Cubic Zirconia (Simulant) · Indeterminate/Rough Cut Irregular
Poor/Niche (shows conchoidal fracturing rather than professional faceting) Cut
Carat
Estimated 10.0+ carats (large visual profile)
Color
Colorless, though showing significant chromatic aberration
Clarity
I2-I3 (Included/Low Clarity)
Shape
Indeterminate/Rough Cut Irregular
Overall Assessment
This object does not possess the structural or optical characteristics of a high-quality gemstone diamond. It appears to be an irregular piece of optical glass, quartz, or a lower-grade simulant.
Cut Quality
Poor/Niche (shows conchoidal fracturing rather than professional faceting)
Brilliance
Low; light is scattered rather than concentrated
Fire
Moderate (visible rainbow dispersion, likely due to material refraction index rather than precision cutting)
Scintillation
Low to None (lacks a defined sparkle pattern)
Proportions
Non-standard; lacks traditional geometric table or pavilion ratios
Symmetry
Poor (asymmetric and irregular)
Polish
Poor (noticeable surface rippling and uneven light reflection)
Fluorescence
Indeterminate without UV source
Inclusions
Extensive internal fracturing, veining, and possible bubbles/voids
Blemishes
Heavy surface abrasion, irregular chipping, and texture
Origin
Likely synthetic or geological common mineral
Treatment Detection
No obvious thermal or chemical treatments detectable from image
Estimated Value
$10 - $150 (Decorative/Specimen value)
Certification Estimate
Unlikely to receive a GIA diamond grade; specialty gem report possible
Investment Potential
Very Low to None
Similar Diamonds
Unfaceted industrial diamonds or cracked glass/quartz samples
Setting Suggestions
Not suitable for traditional prong settings; possibly wire-wrapped or bezel for costume jewelry
Care & Maintenance
Handle with care to avoid further fracturing; clean with a soft dry cloth
Interesting Facts
The material exhibits conchoidal fracturing, which is a key diagnostic feature for quartz and glass, unlike diamond's octahedral cleavage.
