What is Irradiation?
Gemstones are irradiated with a specific aim that is to enhance and deepen their color. It is the process of using electromagnetic radiation to alter the color of a stone. In early 1900’s, Irradiation used by scientists like Bordas and Crookes, they used radium salts to change blue sapphires and diamonds green.
What effect does irradiation have on Topaz or Other Gems?
Irradiation of blue topaz gemstone has created shades not found in natural blue topaz, for example, Sky and London Blue. Also, Topaz stone is not the only gems treated with radiation to change its color. Other gemstones are sometimes irradiated to change their color. For example, Off-color diamonds or we can say browns and brown-yellows diamonds can be irradiated so as to turning them into intense yellows, pinks, browns, greens and blues. Irradiated diamonds are inexpensive than their natural counterparts of comparable clarity grade, size and color. Tourmaline gems can be irradiated to darken pink gems into red ones. All in all, the longer gems are exposed to radiation, the deeper the color.
By the way, not all radiation treatments applied to stones make them radioactive. This is because if they are bombarded with neutrons, then trace elements in the gems can become radioactive. Besides, gemstones can also be treated using gamma radiation, which does not make them radioactive or activated.

This process can take place in an accelerator (electron bombardment), a nuclear reactor (neutron bombardment) or by exposure to gamma rays in an irradiator machine. Usually, it is gamma rays from radioactive elements like cobalt which labs use to irradiate topaz. Depending on the type and duration of irradiation, and the type of heating process used afterward, the outcome varies from sky to Swiss to London blue topaz. London blue is the most expensive and scarcest type because it needs neutron exposure, which is the most expensive process as well as the longest holding times.
