The gemstone irradiation is a process in which a gemstone is artificially irradiated in order to enhance its optical properties. High levels of ionizing radiation can change the atomic structure of the gemstone’s crystal lattice, which in turn alters the optical properties within it.
Are irradiated gemstones safe to wear?
Well, it is true that a lot of gemstones are irradiated, but they’re completely safe to wear so you can relax a little bit! … The general answer is that gemstone color comes from the interaction of the stones with light – some colors are absorbed, some are refracted within the gem, and some are reflected.
Are irradiated gems dangerous?
The NRC has no reason to believe that wearing irradiated gemstones can be harmful. There have been no reported cases of anyone being harmed by wearing them or any other irradiated gems.

Is Rose quartz irradiated?
Quartz crystals of a similar color are called pink quartz. The color can vary from a very bright pink to almost purple. Rose quartz is usually very evenly colored. … Irradiation (both natural or artificial) of rose quartz can lead to the formation of additional smoky quartz centers and according alterations in color.
Are gemstones radioactive?
Additionally, gemstones are, in rare cases, irradiated using neutrons since this is much more complicated. In doing so, small amounts of radioactive substances are produced within the gemstones which in turn emit radiation, but the radiation intensity decays within a relatively short time.
Is Tiger’s Eye dangerous?
Is Tiger’s Eye Dangerous? YES. Certain types of tiger eye contain toxins such as asbestos and silicosis, making it unfit for wear. The fibrous form of asbestos is found in Tiger eye.
How can you tell if a diamond has been irradiated?
Irradiated diamonds come in blue, green, canary yellow, or even pink as well as many other colors. Because this process is permanent, the G.I.A. will grade and certify irradiated diamonds and can also laser inscribe the diamond to notify any potential buyer that the diamond has been irradiated.
What is the rarest color of diamond in the world?
Red diamonds are the rarest of the colored diamonds, with only 20-30 existing in the entire world. They get their beautiful red color from a rare process during their formation, which changes the crystal structure of the diamond and causes light to pass through it differently than colorless diamonds.
Are Black Diamonds irradiated?
Treated color black diamonds can be irradiated so they appear black but they’re actually a very dark green color or they can be subjected to low pressure, high-temperature annealing which induces large-scale graphitization within surface-reaching fractures.
