Name:
Zirkon appears to occur first in Abraham Gottlob Werner's (1780) translation of Axel F. Cronstedt's "Försök till en mineralogie, eller mineral rikets upställning." (1751). Werner adds a short additional comment to Cronstedt's text: " Jargons oder Zirkonen sind weisse, graue, auch blasgelbe und blasrothe Hyazinthen; die öften für Diamante verkauft werden." Werner consider zirkon as an alternative spelling for sargone or jargon.

These latter names, and thereby zircon, descend from medieval French (jargonce), Italian (giarconsia) and Spanish (iargonça). These in turn originates from the old French jagonce. The Dictionnaire Étymologique de l'Ancien Français (2007) provides several references and quotes for jargonce, the oldest from the 12th century.

The origin of jagonce is unknown, but it is related to the medievial Syriac yaqūndā, a similar gemstone. (Smith, R. P., & Hanson, K. C. (Eds.). (2007). Thesaurus syriacus)

German scientists adapted the name zirkon and work by Klaproth, Emmerling and others established zirkon as the preferred spelling in scientific literature. Hauy (1801) in his Traité de minéralogie also adapted the name zircon.

The common association of zircon with Arabic and Persian “azargun” seems to be a modern construct as there are no etymological evidence supporting this association.
Dimorph of:
Zircon Group. The zirconium analogue of Thorite and Hafnon. Zircon-Hafnon Series. The low-pressure dimorph of Reidite.

Zircon, zirconium orthosilicate, is found in most igneous rocks and some metamorphic rocks as small crystals or grains, mostly widely distributed and rarely more than 1% of the total mass of the rock. It is also found as alluvial grains in some sedimentary rocks due to its high hardness. 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). The uranium concentration of zircon is generally very high, between 300 and 600 ppm and a melting temperature of 2550°C, make zircon a good mineral for age dating.

Matura DiamondA misnomer for colourless zircon.
NaegiteGreenish grey to greenish brown anhedral grains, crude crystals or spheroidal aggregates. Originally mis-described as a new U-Th-silicate, without having analyzed for Zr, but within a year it was found to really be a Y-Th-U-rich variety of zircon (or "cyr...

Fluorescence of ZirconHide

Many zircons are fluorescent, but some (mainly metamict ones) are not. Fluorescent zircon, from dull to bright in intensity, shows shades of yellow, golden-yellow and yellow-brown (SW UV). This property is often diagnostic in identification.

Other InformationHide

Thermal Behaviour:
Thermoluminescent
Notes:
Cathodoluminescent
Health Risks:
U- and Th-bearing zircon is radioactive. Gemstones should be tested for radioactivity before being worn on or near the body.
