The name zircon probably originated from the Persion word zargun, which describes the color of the gemstone now known as zircon, jargon, hyacinth, jacinth, or ligure. The impure metal was first isolated by Berzelius in 1824 by heating a mixture of potassium and potassium zirconium fluoride in a small decomposition processs they developed.
Zirconium is found in abundance in S-type stars, and has been identified in the sun and meteorites.
Analysis of lunar rock samples obtained during the various Apollo missions to the moon show a surprisingly high zirconium oxide content, compared with terrestrial rocks. Naturally occurring zirconium contains five isotopes. Fifteen other isotopes are known to exist. Sirconium also occurs in some 30 other recognized mineral species. It is a grayish-white lustrous metal.
