Connected to internal radiation damage, these processes partially disrupt the crystal structure and partly explain the highly variable properties of zircon.

Rock forms when mineral grains (often crystals) grow together.

Granite, diorite, gabbro and basalt are a few types of igneous rock.

Magma is made up of atoms and molecules of melted minerals.

When magma cools the atoms and molecules rearrange to form mineral grains.

Zircon is a common accessory to trace mineral constituent of most granite and felsic igneous rocks.

Due to its hardness, durability and chemical inertness, zircon persists in sedimentary deposits and is a common constituent of most sands.

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%.

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 gold-hued. It occurs as a common accessory mineral in igneous rocks (as primary crystallization products), in metamorphic rocks and as detrital grains in sedimentary rocks.

The crystal structure of zircon is tetragonal crystal system.
