Notes: There is 2 important point that are to be mentioned when talking about Sky Blue Topaz. First of all, while topaz is very hard, the durability of the stone is low. Due to it’s perfect cleavage, a trait that it has in common which diamond. Meaning it can cut, slit or chipped by a sharp blow, so it should be protected from knock, and any shock. Secondly, it is not naturally saturated blues, such as you can find today on the market. Natural Blue topaz, is very rare, it mostly tend to be a very pale blue. Most vivid blues available in the shop have been made by treating white topaz. How? Using irradiation and often heat. The color change is permanent and stable.
Irradiation: The Blue Topaz, there is three way to irradiate it, all three method have different result. First, used to make very pale blue, is exposure to a gamma ray in a cobalt irradiator, this method doesn’t cause radiation. Second, method use electron bombardment in an accelerator, also known as “Linac” treatment and make Sky Blue Topaz. And the third method, is to exposes the stone to fast neutrons in a nuclear reactor, this produces the darker hues known as “London blue”.
Due to residual radioactivity, the irradiated topaz must be held in a secure facility for a specified period of time before it can be released for heating, cutting and polishing. The time varies from a few weeks for topaz irradiated in a linear accelerator to a few years for topaz irradiated in a nuclear reactor. There are very strict rules in place to protect not only consumers but also the cutters and gem dealers who handle these gems on a daily basis.
Once the stone change color, we keeping the Gamma Ray and the Linac for 6 month in a warehouse to make sure their is no radiation. And we keep the London Blue Topaz for two years.
