Physical properties

Formation & geological history

Laboratory-created. Formed via the skull melting process where zirconium dioxide powder is heated to 2,750°C. While naturally occurring Baddeleyite exists, gem-quality cubic zirconia is exclusively synthetic.

Uses & applications

Primarily used in costume jewelry and fashion accessories as a diamond stimulant. The specific item shown is an 'Evil Eye' jewelry connector/charm for bracelets or necklaces.

Geological facts

Cubic zirconia was perfected as a diamond alternative by Soviet scientists in the 1970s. It is much heavier than a diamond (approx. 1.7 times the weight) but less thermally conductive.

Field identification & locations

Identify in jewelry settings by its high dispersion (rainbow 'fire') and lack of natural inclusions. These mass-produced jewelry components are found globally in retail craft and fashion stores.
