Physical properties
Hardness: 8–8.5 Mohs scale; Color: Colorless (clear); Luster: Adamantine; Crystal Structure: Cubic; Specific Gravity: 5.50–5.90.
Formation & geological history
Synthetically produced in laboratories using the skull melting process to stabilize Zirconium Dioxide into its cubic form. While it can occur naturally as 'baddeleyite', the jewelry version is man-made.
Uses & applications
Used extensively in jewelry as a diamond stimulant, for industrial precision components, and in luxury optical coatings.
Geological facts
Cubic Zirconia was first mass-produced in the late 1970s and is much heavier than a natural diamond of the same size. It is often used to imitate high-end diamond tennis bracelets.
Field identification & locations
Identified by its high flash of rainbow 'fire', lack of inclusions under magnification, and significantly lower price point compared to natural gems. Check settings for markings like 'CZ' or '925'.
