Zircon \Zir"con\, n. [F., the same word as jargon. See Jargon a variety of zircon.]

  1. (Min.) A mineral consisting predominantly of zirconium silicate ( Zr2SiO4) occurring in tetragonal crystals, usually of a brown or gray color. It consists of silica and zirconia. A red variety, used as a gem, is called hyacinth. Colorless, pale-yellow or smoky-brown varieties from Ceylon are called jargon.

  2. an imitation gemstone made of cubic zirconia.

Wikipedia
Zircon

Zircon ( or ; including hyacinth or yellow zircon) is a mineral belonging to the group of nesosilicates. Its chemical name is zirconium silicate and its corresponding chemical formula is Zr SiO. A common empirical formula showing some of the range of substitution in zircon is (Zr, REE)(SiO)(OH). Zircon forms in silicate melts with large proportions of high field strength incompatible elements. For example, hafnium is almost always present in quantities ranging from 1 to 4%. The crystal structure of zircon is tetragonal crystal system. The natural color of zircon varies between colorless, yellow-golden, red, brown, blue, and green. Colorless specimens that show gem quality are a popular substitute for diamond and are also known as "Matura diamond".

The name derives from the Persian zargun meaning golden-colored. This word is corrupted into " jargoon", a term applied to light-colored zircons. The English word "zircon" is derived from "Zirkon," which is the German adaptation of this word. Red zircon is called " hyacinth", from the flower hyacinthus, whose name is of Ancient Greek origin.
