[Ice Blue] Cubic Zirconia Necklace in Sterling Silver

Cubic zirconia (CZ) is a synthetic gemstone made from zirconium dioxide (ZrO₂). It is widely used as a diamond simulant due to its close resemblance to diamonds in appearance, but it has different properties. Here’s a deeper dive into what cubic zirconia is:

1. Composition:

• Cubic zirconia is made from zirconium dioxide and is typically created in a laboratory environment. It is a synthetic material, meaning it is not naturally occurring in the same way that diamonds or other gemstones are.

2. Appearance:

• CZ is optically very clear and can be cut in various shapes, just like diamonds. It can exhibit a bright, sparkling appearance, though its brilliance is not quite the same as diamonds or moissanite. It does, however, have a high refractive index, which contributes to its sparkle.
• One noticeable difference between CZ and diamonds is that CZ has more "fire" (the dispersion of light into rainbow colors), which can result in a slightly different sparkle compared to diamonds.

3. Hardness:

• Cubic zirconia is not as hard as diamonds. On the Mohs scale of hardness, CZ ranks about 8-8.5, while diamonds rank a perfect 10. This means that CZ can be scratched or damaged more easily over time, especially if it's exposed to rough conditions or contact with harder materials.

4. Price:

• One of the biggest advantages of cubic zirconia is its affordability. CZ is much cheaper than diamonds, making it a popular alternative for people who want the look of a diamond without the high cost. While a diamond's price is determined by factors like carat, cut, color, and clarity, CZ is much less expensive to produce, making it accessible for budget-conscious buyers.

5. Durability:

• While CZ is fairly durable, it's not as resilient as diamonds. Over time, it can become scratched, lose its brilliance, and develop surface wear. However, with proper care, CZ can last for many years, though it may not have the same lasting shine as diamonds or moissanite.

6. Uses:

• Jewelry: Cubic zirconia is most commonly used in costume jewelry and even high-quality, affordable rings, earrings, necklaces, and bracelets. It can be cut to resemble diamonds and other precious gemstones.
• Decorative Items: CZ is also used in various decorative objects or as a low-cost alternative to other more expensive gemstones in certain luxury items.

7. Difference from Other Gemstones:

• Diamonds: While CZ looks very similar to diamonds at first glance, diamonds are made of pure carbon and are the hardest natural material known, offering greater longevity and value.
• Moissanite: Moissanite is another diamond alternative that is harder and more brilliant than CZ, but more expensive.
