Physical properties
Hardness: 8–8.5 (Mohs scale); Color: Colorless (clear) multi-faceted stones with blue and white enamel; Luster: Adamantine (diamond-like); Structure: Isometric (cubic); Cleavage: Indistinct; Specific Gravity: 5.6–6.0
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.
