Cubic zirconia (CZ) is made from zirconium dioxide and is optically flawless, usually colorless, and hard, making it a popular diamond simulant. Whether used as a standalone stone or in combination with other gemstones, CZ can provide the desired brilliance and elegance for various jewelry designs. Here are some key points about cubic zirconia:

• Appearance: Cubic zirconia stones are often cut and polished to match the brilliance and sparkle of diamonds. They come in various shapes and sizes and can be colorless or have color variations, depending on the manufacturing process.
• Durability: While cubic zirconia is relatively hard and durable, it is not as hard as diamonds. CZ has a Mohs hardness of about 8-8.5, whereas diamonds have a hardness of 10. This means that CZ is more prone to scratches and abrasions over time.
• Uses: Cubic zirconia is commonly used in jewelry, including rings, earrings, necklaces, and bracelets. It is also used in watches, accessories, and even as a substitute for diamonds in some industrial applications.

Maintenance: CZ jewelry requires similar care to diamond jewelry. While it is relatively durable, it is still susceptible to damage from harsh chemicals, scratches, and impacts. Regular cleaning with mild soap and water and gentle handling can help maintain the brilliance of cubic zirconia stones.
