Blue topaz can range from a very light blue to a deeper blue colour. It can also have a slightly turquoise hue, reminiscent of aquamarine. Consumers should be aware that naturally occurring blue topaz is extremely rare. Blue Topaz is a natural blue color gem variety from the Topaz mineral family. It is generally very pale blue in color and is often irradiated artificially to produce a stronger hue and increases its value in the market. Some colorless or pale-yellow topaz are also treated with lilac to produce a rich blue color.
