Potential Diamond Simulant (Cubic Zirconia/Moissanite) - Princess Cut

Carat

Estimated 1.00 - 1.50 carats

Color

Colorless (D-F range equivalent)

Clarity

VS1 - VVS2 (Eye Clean)

Shape

Princess Cut

Overall Assessment

The stone displays characteristics highly representative of a diamond simulant like Cubic Zirconia, specifically due to the 'rainbow' fire dispersion and lack of visible inclusions. Professional thermal testing is required for definitive material identification.

Cut Quality

Very Good

Brilliance

Moderately high white light return.

Fire

High dispersion; exhibiting strong flashes of spectral colors suggesting a simulant.

Scintillation

Crisp pattern of light and dark squares, typical of princess cuts.

Proportions

Standard square princess proportions with a flat table and sharp corners.

Symmetry

Good

Polish

Good

Fluorescence

None

Inclusions

No significant internal inclusions visible to the naked eye; likely internally clean.

Blemishes

Minor surface abrasions consistent with handling on a simulant material.

Origin

Likely manufactured/synthetic due to high dispersion and clarity.

Treatment Detection

None apparent; likely an untreated synthetic material.

Estimated Value

$10 - $200 (assuming simulant) or $2,500 - $6,000 (if natural/lab diamond).

Certification Estimate

Unlikely to be sent to GIA/AGS if it is a simulant; IGI for lab-grown/simulant.

Investment Potential

Low; simulants do not retain significant resale value.

Similar Diamonds

CZ princess cuts or high-quality Moissanite square cuts.

Setting Suggestions

Classic 4-prong solitaire in Platinum or 14k White Gold to protect the corners.

Care & Maintenance

Clean with warm soapy water and a soft brush; avoid hitting corners against hard surfaces.

Interesting Facts
