Cubic Zirconia / Simulated Diamond
Cubic Zirconia / Simulated Diamond · Oval Brilliant
Good to Very Good (standard brilliant faceting for a simulated gemstone) Cut
Carat
Estimated approximately 3.0 to 4.0 carats based on visual proportions relative to human fingers.
Color
Colorless (equivalent to D-E on the diamond scale)
Clarity
Estimated internally flawless (IF) visually, as no obvious inclusions are seen under this magnification.
Shape
Oval Brilliant
Overall Assessment
The gemstone shown is an oval brilliant-cut cubic zirconia simulant displaying high dispersion and colorless clarity, intended purely for fashion or costume jewelry use rather than as a precious gem investment.
Cut Quality
Good to Very Good (standard brilliant faceting for a simulated gemstone)
Brilliance
High white light return, though differing in dispersion pattern compared to genuine diamond.
Fire
Noticeably higher dispersion (fire) than a natural diamond, which is a characteristic trait of cubic zirconia.
Scintillation
Good flash effect with alternating bright and dark areas as the stone moves.
Proportions
Standard commercial proportions with a medium table and adequate pavilion depth to prevent a complete 'window' effect.
Symmetry
Good; overall oval symmetry appears balanced with minor variations in facet junctions.
Polish
Good; smooth facet surfaces with standard commercial finishing.
Fluorescence
None observed under normal ambient light
Inclusions
None visible under macroscopic examination, typical of synthetic simulants.
Blemishes
Minor surface wear or micro-scratches possible due to lower hardness compared to genuine diamond.
Origin
Synthetic / Man-made laboratory simulant
Treatment Detection
None required; synthetic cubic zirconia by nature.
Estimated Value
Low commercial value ($10 - $50 USD) as a fashion jewelry simulant.
Certification Estimate
Not applicable for grading laboratories such as GIA or AGS, as they do not issue diamond grading reports for synthetic simulants.
Investment Potential
None; simulant stones do not hold or appreciate in resale value.
Similar Diamonds
High-grade lab-grown moissanite or lab-created diamond alternatives.
Setting Suggestions
Versatile for sterling silver, platinum, or white gold settings such as a solitaire ring or halo design.
Care & Maintenance
Clean with warm soapy water and a soft brush; avoid harsh chemicals and ultrasonic cleaners if mounted in delicate costume settings, and store separately to prevent scratching softer materials.
Interesting Facts
Cubic zirconia has a cubic crystalline form of zirconium dioxide and was first mass-produced for commercial use in the 1970s.
