The zirconium atom has a radius of 160 pm and a Van der Waals radius of 186 pm. Zirconium was discovered by Martin Heinrich Klaproth in 1789 and first isolated by Jöns Jakob Berzelius in 1824. In its elemental form, zirconium has a silvery white appearance that is similar to titanium. Zirconium's principal mineral is zircon (zirconium silicate).

Zircon, Zirconia, Zirconium Minerals - ThoughtCo

Zircon makes a nice gem but it's out of favor these days. Zircon—zirconium silicate or ZrSiO 4 —is a hard stone, ranking 7½ on the Mohs scale, but other stones are harder and its colors aren't unique.Tradition has a slim dossier on zircon; one site says that it was reputed to "aid sleep, bring prosperity, and promote honor and wisdom," but hey, just having the money to own jewels is good ...

Zirconium - Wikipedia

Zirconium is a chemical element with the symbol Zr and atomic number 40. The name zirconium is taken from the name of the mineral zircon (the word is related to Persian zargun (zircon;zar-gun, "gold-like" or "as gold")), the most important source of zirconium. It is a lustrous, grey-white, strong transition metal that closely resembles hafnium and, to a lesser extent, titanium.

Zirconium and Hafnium Statistics and Information - USGS

The principal economic source of zirconium is the zirconium silicate mineral, zircon (ZrSiO4). Zircon is the primary source of all hafnium. Zirconium and hafnium are contained in zircon at a ratio of about 50 to 1. Zircon is a coproduct or byproduct of the mining and processing of heavy-mineral sands for the titanium minerals, ilmenite and rutile, or tin minerals.
