Natural Colors
The natural colors of zircon are beautiful browns, yellows, strong greens, and bright reds. They are natural colors because they were not treated with heat. (Heat treatment creates both colorless and blue zircon.) These zircons are from Sri Lanka. - Photo courtesy Alan Jobbins

Colorless Zircon
Colorless zircon is one of the most bright and sparkling non-diamond gems. It was often used as a lower-cost diamond substitute in the nineteenth century (1800s). - Photo by Robert Weldon/GIA, Dr. Eduard J. Gübelin Collection
Wear and Tear
Zircons can be brittle, and they might show damaged facet edges because of wear and tear. Facets [fas-ets] are the flat surface areas of a cut gem. - Photo by Tino Hammid/GIA
