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 ]
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 ...
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.
Citrine “A powerful gemstone crystal in a range of deep yellows, oranges, and yellow-cream-white, the citrine gemstone is said to bring abundance and wealth into one’s life,” Salzer says.
The irradiation process is widely practiced in jewelry industry [45] and enabled the creation of gemstone colors that do not exist or are extremely rare in nature. [46] 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 ...
The first two methods can only modify color, usually to turn an off-color Cape series stone (see Material properties of diamond: Composition and color) into a more desirable fancy-colored stone. Because some irradiation methods produce only a thin "skin" of color, they are applied to diamonds that are already cut and polished.
Across cultures, different stones can symbolize or provide aide for different things. An example of this is rose quartz . In Egypt, it was believed rose quartz could prevent aging , but the Romans used rose quartz as a seal to signify ownership , while in the Middle Ages it was used in healing potions, today rose quartz is known as the "love ...
Similarly, it allows for a reasonable amount, defined as up to 25 pounds a day and 250 pounds per year, of common fossils, gemstones and certain other materials for personal use.
