Natural Precious Topaz is available in several different colors: Colorless (White), Yellowish-Orange with some Peach in it (Imperial) as well as Light Blue, Green, Yellow, Orange, and Pink. Topaz is mainly mined in Brazil, Mexico, Sri Lanka, Africa, and China.
Blue is the most popular color used in jewelry. Some Blue Topaz is produced in nature, however, the natural shade is generally too pale to excite any interest. The colors like London Blue, Sky Blue, Swiss Blue, and Maxi Blue start as a near colorless to bluish-gray to silvery-gray to brown to brownish green in color, and they are irradiated with gamma or electron Irradiation to a shade of brown, then heated to produce bold colors like the blue-green color "London Blue", the light blue color "Sky Blue", the medium blue color "Swiss Blue", and the more intense blue color "Maxi Blue". The value increases with the intensity of color, provided it is attractive.
TREATMENTS - Natural Imperial Topaz is not treated. Natural Yellow Topaz is not treated. Natural Pink Topaz is typically not treated, however sometimes peach colored topaz can be pinked by gentle heating, which is a permanent process. Swiss Blue, Maxi Blue, and London Blue Topaz are Natural Topaz Gems, however, the blue colors are created by gamma or electron irradiating, followed by heating. The typical treatment process for these blue colors is a permanent process that does not adversely affect the performance and durability of the gemstone, so there's no need to worry when you see this enhancement disclosed. There are many other color varieties of Topaz, like Mystic Topaz, and other unusual colors that did start out as Natural Topaz Gems, but these have been Coated to create the unusual color varieties. The Coating process is not a permanent treatment, when scratched the original color is visible.
CARE - Jewelry featuring Topaz should not be cleaned in an ultrasonic or steam cleaner. I recommend Ionic Cleaners and/or warm, soapy water and a soft brush as the best way to clean Topaz jewelry.
