The zirconium-containing mineral zircon and related minerals (jargoon, hyacinth, jacinth, ligure) were mentioned in biblical writings but the mineral was not known to contain a new element until 1789 when Martin Heinrich Klaproth analyzed a jargoon from the island of Ceylon (no Sri Lanka). Zirconium metal was first obtained in an impure form in 1824 by Jöns Jacob Berzelius by heating a mixture of potassium and potassium zirconium fluoride in an iron tube.
