Zircon

Nesosilicates

Zircon ( /ˈzɜːrkɒn/ belonging to the group of nesosilicates , and it is a source of the metal zirconium, and its corresponding chemical formula is Zr. A common empirical formula showing some of the range of substitution in zircon is (Zr1–y, REE y)(SiO4)1–x(OH)4x–y. Zircon forms in silicate 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 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.

Yellow, orange and red zircon is also known as "hyacinth from the flower hyacinthus , whose name is of Ancient Greek origin.
