Zircon is a mineral belonging to the group of nesosilicates. Its chemical name is zirconium silicate, and its corresponding chemical formula is ZrSiO4. Here are some key points about zircon:

1. Properties: Zircon is known for its high refractive index and strong dispersion, which gives it a brilliant sparkle similar to diamonds. It is often used as a gemstone in jewelry.

2. Uses: Beyond its use in jewelry, zircon is also used in various industrial applications. It is a significant source of zirconium, which is used to produce zirconium dioxide (zirconia), a material with high thermal stability and resistance to corrosion. Zircon is also used in the production of ceramics, refractory materials, and in the foundry industry.

3. Occurrence: Zircon is found in igneous, metamorphic, and sedimentary rocks. It is often mined from heavy mineral sands. Major producers of zircon include Australia, Nigeria, South Africa, and the United States.

4. Geological Importance: Zircon crystals can survive geological processes like erosion, transport, and metamorphism, making them valuable for geochronology. They are used in radiometric dating to determine the age of rocks.

5. Market: The price of zircon can vary depending on its quality and market demand. High-quality zircon used in jewelry can be quite expensive, while industrial-grade zircon is priced based on its utility in various applications.
