What is cubic zirconia?

Cubic zirconia (CZ) is a synthetic gemstone that is visually very similar to diamond. Here's some information about it:

• What is it? CZ is the cubic crystalline form of zirconium dioxide (ZrO2). It is a man-made material, meaning it's created in a lab and not found naturally.

• Appearance: It's known for its high hardness, optical clarity, and brilliance, which is why it's frequently used as a <a href="https://www.wikiwhat.page/kavramlar/diamond%20substitute">diamond substitute</a>.

• Manufacturing: CZ is created through a melting and crystallization process involving high temperatures. This allows for controlled production of flawless, high-quality stones.

• Properties: Compared to diamond, CZ is harder (although not as hard), heavier, and more optically clear. It also disperses more light, giving it a more colorful "fire" than a diamond. This dispersion gives CZ a rainbow like appearance in bright light.

• Uses: Cubic zirconia is widely used in <a href="https://www.wikiwhat.page/kavramlar/jewelry">jewelry</a> of all kinds, including rings, earrings, necklaces, and pendants. It's a popular, affordable alternative to diamonds and other precious gemstones.

• Distinguishing CZ from Diamond: While visually similar, CZ can be distinguished from diamond using several tests. CZ is heavier than diamond. Jewelers typically use thermal conductivity testers to identify the difference between the two. <a href="https://www.wikiwhat.page/kavramlar/diamond%20tester">Diamond testers</a> measure how quickly heat travels through a stone, which differs substantially between diamond and CZ.
