Back to Rocks and Minerals Articles Peter Russell and Tharsika Tharmanathan Zinc (Zn) is a bluish-white shiny metal that is fragile at room temperature, but becomes malleable at 100 degrees Celsius. Zinc is one of the most common elements in the Earth's crust. It is found in soil, air, and water and is present in food. Zinc was used in Rome and China more than 2000 years ago

Sphalerite is the chief ore of zinc, and gem quality specimens are sometimes found in zinc mines. But most sphalerite contains iron, and it is black in color and completely opaque when the iron content is high. The rare gem quality specimens have a low iron content and a high degree of transparency.
