RedPurplish Blue Mixed Color Firework Cut Cubic Zirconia

Cubic zirconia (CZ) is a synthetic crystalline material with the chemical composition zirconium dioxide (ZrO₂). It is produced by melting zirconium powder at extremely high temperatures (approximately 2750°C), adding stabilizers such as yttrium or calcium, and then slowly cooling it to crystallize. Its physical properties are exceptional: with a Mohs hardness of 8.5, it rivals sapphire in durability and exhibits outstanding wear resistance. Its refractive index (2.15–2.18) surpasses that of diamond (2.42), while its dispersion value (0.058–0.066) is twice that of diamond, resulting in exceptionally brilliant fire. Its density of 5.5–6.0 g/cm³ is slightly higher than diamond's, allowing differentiation by weight.

Its primary applications are concentrated in the jewelry sector, where it serves as a perfect substitute for diamonds in the creation of rings, necklaces, earrings, and other pieces. Additionally, due to its high hardness and heat resistance, it is utilized in industrial abrasives, optical lenses, and coatings for medical instruments.

The popularity of cubic zirconia stems from its multiple advantages combined. Its cost is only one percent or even less than that of natural diamonds, yet it offers 95% visual similarity, allowing ordinary consumers to enjoy a "diamond-like" sparkling experience.

Its higher dispersion value creates a more intense rainbow effect (fire) under light, delivering a visual impact that can even outshine diamonds, satisfying the public's intuitive desire for brilliance.

Synthetic technology enables precise control over color (such as colorless, pink, blue, black, etc.) and clarity, producing flawless and highly consistent products that support designers in realizing large-scale, serialized creations.

Commonly used in S925 series Jewelry, mostly in earring
