Blue Topaz - December's Alternative Birthstone
Blue topaz very rarely occurs naturally. Its color is caused by treatment. Almost all blue topaz in the market is colorless topaz that has been irradiated and heat treated to create its beautiful blue color. This treatment results in three commonly seen shades; light aquamarine Sky Blue, vivid Swiss Blue and deep ocean London Blue topaz.
Blue topaz looks similar to blue zircon in color but is available in a wide variety of shapes and sizes at affordable prices. This quality makes blue topaz extremely popular and the perfect choice as the alternative December birthstone!
