Gemstone irradiation is a process in which a gemstone is exposed to artificial radiation 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. [ 1 ]
When the mark walks into the temple, there will be a gentleman praying inside. That person will tell him about a scheme by the government [5] which allows people to buy jewelry duty-free and make a profit when the gems are shipped to their home country, adding that today is the last day of this scheme.
Electron-beam processing or electron irradiation (EBI) is a process that involves using electrons, usually of high energy, to treat an object for a variety of purposes. This may take place under elevated temperatures and nitrogen atmosphere.
The irradiation process is widely practiced in jewelry industry [12] and enabled the creation of gemstone colors that do not exist or are extremely rare in nature. [13] However, particularly when done in a nuclear reactor, the processes can make gemstones radioactive. Health risks related to the residual radioactivity of the treated gemstones ...
Numbered clockwise from left bottom: (1) 2×2 mm initial; top row (2,3,4) irradiated by different doses of 2 MeV electrons; bottom right (5,6) irradiated by different doses and annealed at 800 °C. Sir William Crookes , a gem fancier as well as a chemist and physicist , was the first to discover radiation's effects on diamond color when in 1904 ...
