Physical properties
Hardness: 8.0-8.5 Mohs scale; Color: Deep red (vibrant, saturated); Luster: Adamantine (diamond-like); Crystal Structure: Cubic; Specific Gravity: 5.5-6.0
Formation & geological history
Laboratory-created through the Skull Melting process, which involves heating powdered zirconium and stabilizers to approximately 4,982°F (2,750°C).
Uses & applications
Primary use in jewelry as a durable, affordable alternative to natural gemstones like Garnet or Ruby. Used in high-end costume jewelry.
Geological facts
Red cubic zirconia is known for its high dispersion—the ability to split light into spectral colors—giving it more 'fire' than many natural gemstones.
Field identification & locations
Identify in the field by checking for high density (specimen will feel heavier than glass) and checking for inclusions; cubic zirconia is typically flawless. These are commonly found in commercial jewelry retail.
