Distinction Between Red Zircon and Cubic Zirconia
The gemstone market often witnesses confusion between red zircon and cubic zirconia, primarily due to the similarity in their names. However, these two materials are fundamentally different in terms of origin, structure, and value. Understanding the distinctions between these two is crucial for gem enthusiasts, jewelry buyers, and professionals in the gem and jewelry industry.
Origin and Composition
| Aspect | Red Zircon | Cubic Zirconia |
|---|---|---|
| Origin | Natural mineral | Lab-created synthetic material |
| Composition | Zirconium Silicate (ZrSiO₄) | Zirconium Dioxide (ZrO₂) |
Red zircon is a natural gemstone formed over millions of years within the Earth’s crust, while cubic zirconia (CZ) is a synthetic material created in a laboratory setting within a short period.
Physical and Optical Properties
| Property | Red Zircon | Cubic Zirconia |
|---|---|---|
| Hardness | 7.5 on the Mohs scale | 8.5 on the Mohs scale |
| Refractive Index | 1.810 – 2.024 | 2.15 – 2.18 |
| Dispersion | 0.039 | 0.058 – 0.066 |
| Specific Gravity | 4.60 – 4.70 | 5.5 – 5.9 |
Cubic zirconia possesses a higher hardness and refractive index compared to zircon, making it more diamond-like in appearance. Its higher dispersion also gives it more fire, which is the splitting of white light into its spectral colors.
Value and Usage
Red zircon, being a natural gemstone, holds a higher value in the gemstone market, cherished for its unique color, historical significance, and natural beauty. It’s widely used in various types of jewelry including rings, pendants, and earrings.
