Zircon: Mineral information, data and localities.

Zircon has a high refraction index and, when the crystals are large enough, is often used as a gemstone. In geology, zircon is used for radiometric dating of zircon-bearing rocks (using isotopes of U which is often present as an impurity element, as is Th, radiogenic Pb, Hf, Y, P, and others). Compare 'UM1984-36-SiO:CaNaZr'.
