Zirconium Oxide | Encyclopedia.com
About 95 percent of all zirconium produced is converted into a compound before being used. The two most common compounds made are zircon (zirconium silicate) and zirconia (zirconium oxide). Naturally occurring zircon is in demand as a gemstone. It is polished, cut, and used for jewelry and art.

Zircon - The Gemology Project
Zircon is a mineral species that can be broadly defined as a zirconium silicate containing trace amounts of the radioactive minerals hafnium, uranium and thorium. Over time, these radioactive components break down the lattice of the crystal, eventually (over tens of thousands of years) destroying the internal crystal lattice and leaving it with ...

Zirconium - Wikipedia
Naturally occurring zirconium is composed of five isotopes. 90 Zr, 91 Zr, 92 Zr and 94 Zr are stable, although 94 Zr is predicted to undergo double beta decay (not observed experimentally) with a half-life of more than 1.10×10 17 years. 96 Zr has a half-life of 2.4×10 19 years, and is the longest-lived radioisotope of zirconium.
