Lookalikes

Commonly confused with

Cubic zirconia, diamond, glass, synthetic spinel.

Market context

Treatments and imitations

Heat commonly produces blue and colorless stones; abrasion and radiation damage affect durability.

Observation guide

What to check

Use magnification for doubled back facets and wear, but laboratory testing is safest for valuable stones.

Use visual checks to ask better questions, not to replace qualified testing when identity, treatment, value, or origin is consequential.

Practical handling

Care and safety

Avoid knocks, heat shock, steam, and ultrasonic cleaning; facet edges can abrade.

Responsible buying

Ethics and sourcing

Always distinguish natural zircon from cubic zirconia and disclose heat treatment.
