Currently, the most popular color for this gem is the blue zircon. Most blue zircon, which is considered an alternate birthstone for December, is normally a pastel to medium blue in color, but some exceptional gems have a bright blue color. Beyond blue, Zircon is also available in green, deep red, yellow, brown, and orange.
Zircon is a type of gemstone. It's desirable because of the range of colors that it comes in and because it's less expensive than other gemstones, especially diamonds. Although it sometimes gets confused with cubic zirconia, the two are only similar in name.
