Overall Assessment

Symmetry
Good
Polish
Very Good
Fluorescence
None
Inclusions
None visible under magnification; common for synthetic simulants.
Blemishes
Minor surface abrasions consistent with use.

Estimated Value
$5 - $20 USD (Materials and setting value only)
Certification Estimate
Unlikely to be graded by GIA as it is not a diamond; local jeweler appraisal possible.
Investment Potential

Similar Diamonds
Fashion jewelry white sapphires or low-cost lab-grown diamonds.
Setting Suggestions
Bezel set in yellow gold (as shown), suitable for daily wear pendants.
Care & Maintenance
Ultrasonic cleaners are safe; avoid harsh chemicals to maintain the metal finish.
Interesting Facts
Cubic Zirconia has 1.7 times the dispersion of a diamond, which is why it often looks 'more colorful' than the real thing.
