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." [1] Zircon is one of the three birthstones for December; the other two are Tanzanite and Turquoise. [2]
"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." [3] "Zircon resembles diamond in luster and fire and colorless zircons have been mistaken for diamonds by experienced jewelers." Notable occurances are located in Seiland, Norway; Pakistan; Russia; Bancroft and Sudbury, Ontario, Canada and New Jersey and Colorado, USA.[4] Zircon belongs to the Silicates mineral class.
