Likely Cubic Zirconia (CZ) or similar diamond simulant
Likely Cubic Zirconia (CZ) or similar diamond simulant · Round Brilliant
Good to Very Good (symmetrical faceting visible) Cut
Carat
Estimated 1.50 - 2.00 carats
Color
Likely D-E (exceptionally white/colorless)
Clarity
Internally Flawless (IF) characteristic of simulants
Shape
Round Brilliant
Overall Assessment
Based on the high clarity, lack of color, and high dispersion relative to historical pricing, this stone is most likely a high-quality Cubic Zirconia simulant rather than a natural or lab-grown carbon diamond.
Cut Quality
Good to Very Good (symmetrical faceting visible)
Brilliance
High; exhibits white light return typical of high-quality stimulants
Fire
High; exhibits significant rainbow dispersion (fire)
Scintillation
Moderate; the sparkle pattern is somewhat broader than a natural diamond
Proportions
Standard round brilliant proportions appear consistent with high-refractive index simulants
Symmetry
Good
Polish
Very Good
Fluorescence
None visible under current lighting
Inclusions
None visible to the naked eye; lacks the typical inclusions found in natural diamonds of this size
Blemishes
Possible minor surface abrasions consistent with softer materials like CZ
Origin
Laboratory manufactured
Treatment Detection
N/A as the material is likely synthetic simulant
Estimated Value
$10 - $30 (market value for high-quality cubic zirconia)
Certification Estimate
Unlikely to be graded by GIA/AGS; would likely be identified as a simulant by IGI
Investment Potential
Negligible; simulants do not retain resale value
Similar Diamonds
Swarovski crystals or high-end CZ jewelry
Setting Suggestions
A simple six-prong silver or white gold plated setting would complement the size
Care & Maintenance
Clean with mild soap and warm water; avoid harsh chemicals as the material can become cloudy over time
Interesting Facts
Cubic Zirconia is nearly 1.7 times denser than a real diamond, meaning a CZ will feel heavier than a diamond of the same size
