Color
Colorless (equivalent to D-E scale)
Clarity
Internally Flawless (simulated high grade, typical for CZ)
Shape

Overall Assessment
An attractive, colorless oval-cut cubic zirconia simulant exhibiting good brilliance and fire, suitable for fashion jewelry purposes but lacking the physical properties and value of a genuine diamond
Cut Quality
Very Good
Brilliance
High white light return, though slightly softer dispersion than natural diamond
Fire
Noticeable dispersion (rainbow flashes) slightly higher than a typical diamond due to higher refractive index dispersion
Scintillation
Good sparkle with standard facet pattern flash
Proportions
Standard standard commercial cutting proportions with moderate table and pavilion depth
Symmetry
Good symmetrical alignment of facets
Polish
Good standard commercial polish
Fluorescence
None observed
Inclusions
None visible under optical examination (characteristic of man-made simulants)
Blemishes
Minor surface abrasions likely from handling
Origin
Laboratory-synthesized Cubic Zirconia
Treatment Detection
None required; synthetic material by nature
Estimated Value
$10 - $30 USD (retail value as a simulant gemstone)
Certification Estimate
Not typically certified by major gemological labs like GIA or AGS due to being a simulant
Investment Potential
None; cubic zirconia holds no resale or investment value
Similar Diamonds
High-grade Moissanite or lab-grown white sapphire simulants
Setting Suggestions
Sterling silver, white gold, or platinum prong or bezel setting
Care & Maintenance
Clean with warm soapy water and a soft brush; avoid harsh chemicals and ultrasonic cleaners if mounted in delicate settings
Interesting Facts
Cubic zirconia was first synthesized for commercial use in the 1970s and remains the most popular diamond simulant in the world due to its affordability and visual similarity
