'''Zircon''' is a mineral, gem, and birthstone. Zircons are commercially mined for the metal [[zirconium]]. "More than 95% of current world production of zirconia and zirconium chemicals comes from processing of zircon. Zircon is processed in a number of locations world wide but [[China]] currently dominates supply of processed zirconium products and world output is around 96,000 tonnes." <ref>[http://www.alkane.com.au/projects/nsw/dubbo/DZP%20Summary%20June07.pdf The Dubbo Zirconia Project]</ref> Zircon is one of the three [[birthstone]]s for December; the other two are [[Tanzanite]] and [[Turquoise]]. <ref>[http://www.americangemsociety.org/birthstones.htm?gclid=CLu6o5CW-pACFRsTawodHiK31Q American Gem Society: Traditional Birthstones]</ref>

*"Zircon is often confused with [[Cubic Zirconia]]. Cubic Zirconia, a synthetic, inexpensive Diamond simulant, resembles colorless Zircon and has a similar sounding name. However, the two are totally separate materials, and have no connection with each other." <ref>[http://www.minerals.net/mineral/sort-met.hod/alphabet/abcdsort.htm Minerals.net]</ref>

==Zircon and Creationism==
Zircon has recently become a subject of interest for [[Creationist]]s. Studies of the rate at which radioactive particles in the zircon release [[helium]] have shown that the zircons found today contain far to much helium to be more than 14,000 years old. <ref>http://www.icr.org/pdf/research/Helium_ICC_7-22-03.pdf</ref> This has been used to support the idea of a young Earth.
