Blue Topaz

Sky Blue Topaz loose sale price & Swiss Blue Topaz Gemstone Information London

starts as an off color, usually bluish-gray to silvery-gray in color, and it is irradiated with gamma or electron Irradiation, in conjunction with heat 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".  These colors become permanent treatments to give the gem a very bright, durable, and attractive color, appropriate for any kind of jewelry.  There are several other types of treatments being used on some of the Topaz on the market to produce a variety of other colors, but most of those treatments are only on the surface of the gem and/or not permanent treatments, therefore we will not offer them.
