Gem Radiation Treatment
Gem Radiation Treatment

Today many gems are also radiation -treated; though this is not as permanent as heating and often enough the gems return to their original colors, as the effects of the treatment slowly subside. Some blue, yellow and orange sapphires found in the market today are radiation-treated and their color will fade within a few years of the treatment. Some beryl gems are radiated blue but also fade back to colorlessness or faint hues of green or yellow. Radiation treatment is especially common in pearls [to produce ‘black' or ‘blue-black' pearls], tourmaline [ to enhance the rare pastel shades of purple, purple-pink and reds], kunzite [for darkening], topaz [to create blues, greens, yellow and orange] and yellow beryl [ to deepen the yellow undertones]. It's not an attractive piece of information to tell any potential customer, so divulging information about a radiation-treated gem will be difficult. No-one really wants to consider how much of the radiation within the gem affects the person wearing it and no-one has yet clearly stated that it may be a health risk. Some blue topazes have been found to be dangerously radioactive and are regularly tested in the U.S, but as you can never really tell where the gem originated it's not a good idea to trust even U.S-sold topaz these days without testing. Some efforts are being made today to determine whether or not radiation treatment is trustworthy, and to establish a set standard of radiation levels that will be accepted world-wide.
