Zircon Group.The zirconium analogue of Thorite and Hafnon. Zircon-Hafnon Series.The low-pressure dimorph of Reidite. Zircon, zirconium orthosilicate, is found in most igneous rocks and some metamorphic rocks as small crystals or grains, mostly widely distributed and rarely more than 1% of the total mass of the rock.

These zircon properties are close enough to the properties of diamond to account for centuries of confusion between the two gems. Zircon occurs in an array of colors. Its varied palette of yellow, green, red, reddish brown, and blue hues makes it a favorite among collectors as well as informed consumers. Zircon Description. Zircon History and Lore

Hadean zircon is the oldest-surviving crustal material from the Earth's earliest geological time period, the Hadean eon, about 4 billion years ago. Zircon is a mineral that is commonly used for radiometric dating because it is highly resistant to chemical changes and appears in the form of small crystals or grains in most igneous and metamorphic host rocks.

The principal economic source of zirconium is the zirconium silicate mineral, zircon (ZrSiO4). Zircon is the primary source of all hafnium. Zirconium and hafnium are contained in zircon at a ratio of about 50 to 1. Zircon is a coproduct or byproduct of the mining and processing of heavy-mineral sands for the titanium minerals, ilmenite and rutile, or tin minerals.

In fact, a tiny mineral fragment of Zircon 4.4 billion years old discovered in Western Australia is the earth’s oldest known object. Perhaps it should be said that ‘Zircons are forever’!
