Likely Diamond Simulant (Cubic Zirconia or Moissanite)

Likely Diamond Simulant (Cubic Zirconia or Moissanite) · Round Brilliant

Fair to Good; shows unusually thick girdle and shallow pavilion angles Cut

Likely Diamond Simulant (Cubic Zirconia or Moissanite) - Round Brilliant

Carat

Estimated 1.5 - 2.0 carats based on size relative to wood grain

Color

Visual E-F (Colorless)

Clarity

Internally Flawless (IF) to VVS1 based on lack of visible inclusions

Shape

Round Brilliant

Overall Assessment

The stone displays visual characteristics strongly consistent with a diamond simulant, such as Cubic Zirconia. The lack of natural inclusions, the specific 'fire' pattern, and the soft facet junctions suggest it is not a natural earth-mined diamond.

Cut Quality

Fair to Good; shows unusually thick girdle and shallow pavilion angles

Brilliance

Moderate; shows 'glassy' appearance rather than the internal light return of a diamond

Fire

High; displays prominent rainbow spectral flashes (fire) which often exceeds natural diamond in stimulants

Scintillation

Broad, blocky flashes rather than the intricate needle-like sparkle of a high-quality diamond

Proportions

High table percentage with a disproportionately thick girdle and shallow depth

Symmetry

Fair; facet junctions appear slightly rounded or misaligned

Polish

Good; surface shows high luster but soft facet edges typical of softer stimulants

Fluorescence

Inconclusive from image; likely None

Inclusions

None visible at macroscopic level; characteristic of mass-produced simulants

Blemishes

Minor surface abrasions possible; facet edges show less sharpness than natural diamond

Origin

Synthetic (Lab-manufactured simulant)

Treatment Detection

Not applicable for simulants; no signs of diamond-specific coatings

Estimated Value

$10 - $50 USD if Cubic Zirconia; $100 - $300 if Moissanite

Certification Estimate

Likely would not be accepted by GIA/AGS for diamond grading; may receive a 'Simulant' report from IGI

Investment Potential

Very Low; simulants do not hold resale value and are considered decorative items

Similar Diamonds

Swarovski Zirconia or high-grade Charles & Colvard Moissanite

Setting Suggestions

Simple 4-prong silver or 14k white gold solitaire setting for costume jewelry

Care & Maintenance

Clean with warm soapy water and a soft brush; avoid harsh chemicals that can dull the surface of simulants

Interesting Facts

The 'rainbow' flash visible on the table is a classic sign of high dispersion often found in Moissanite or CZ, which can exceed the fire of a real diamond.
