zir·con

 (zûr′kŏn′)
n.
A brown to colorless mineral, ZrSiO4, which is heated, cut, and polished to form a brilliant blue-white gem.

[German Zirkon (originally in obsolete scientific German Zirkonerde, zirconium oxide, coined by German chemist Martin Heinrich Klaproth (1743-1817), who first isolated it from a jacinth), probably partly from Arabic zarqūn, minium, bright red (from Persian zargūn, gold-colored, from Middle Persian zargōn, golden : zarr, zar-, golden from Old Iranian *zarna-; see ghel- in Indo-European roots + gōn, color, from Old Iranian *gaona-; akin to Sanskrit guṇaḥ, string, thread, quality), and partly from European terms for "jacinth" such as French jargon (from Old French jargonce, ultimately from Latin hyacinthus; see hyacinth).]

zircon

(ˈzɜːkɒn)
n
(Minerals) a reddish-brown, grey, green, blue, or colourless hard mineral consisting of zirconium silicate in tetragonal crystalline form with hafnium and some rare earths as impurities. It occurs principally in igneous rocks and is an important source of zirconium, zirconia, and hafnia: it is used as a gemstone and a refractory. Formula: ZrSiO4
[C18: from German Zirkon, from French jargon, via Italian and Arabic, from Persian zargūn golden]

zir•con

(ˈzɜr kɒn)

n.
a mineral, zirconium silicate, ZrSiO4, occurring in small tetragonal crystals or grains of various colors, usu. opaque: used as a gem when transparent.
[1785–95; < German Zirkon]
