Zircon ( or ) is a mineral belonging to the group of nesosilicates. Its chemical name is zirconium silicate, and its corresponding chemical formula is ZrSiO4. A common empirical formula showing some of the range of substitution in zircon is (Zr1–y, REEy)(SiO4)1–x(OH)4x–y. 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 colour of zircon varies between colourless, yellow-golden, red, brown, blue and green.
The name derives from the Persian zargun, meaning “gold-hued”. 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. Yellow, orange and red zircon is also known as “hyacinth”, from the flower hyacinthus, whose name is of Ancient Greek origin.
A mineral occurring in tetragonal crystals, usually of a brown or grey colour and consisting of silica and zirconia.
