Beryl is a mineral composed of beryllium aluminium cyclosilicate with the chemical formula Be3Al2(SiO3)6. Well-known varieties of beryl include emerald and aquamarine.
Naturally occurring, hexagonal crystals of beryl can be up to several meters in size, but terminated crystals are relatively rare. Pure beryl is colorless, but it is frequently tinted by impurities, possible colors are green, blue, yellow, red (the rarest), and white.
The name “beryl” is derived from Greek βήρυλλος beryllos which referred to a “precious blue-green color-of-sea-water stone”, akin to Prakrit verulia, veluriya (“beryl”). The term was later adopted for the mineral beryl more exclusively.
When the first eyeglasses were constructed in 13th century Italy, the lenses were made of beryl (or of rock crystal) as glass could not be made clear enough. Consequently, glasses were named Brillen in German.
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.
As a result, the gemstone’s color may be significantly altered or the visibility of its inclusions may be lessened. The process, widely practised in jewelry industry, is done in either a nuclear reactor for neutron bombardment, a particle accelerator for electron bombardment, or a gamma ray facility using the radioactive isotope cobalt-60.
Irradiation has enabled the creation of gemstone colors that do not exist or are extremely rare in nature.
The term irradiation is a very broad one, which covers bombardment by subatomic particles as well as the use of the full range of electromagnetic radiation, including (in order of increasing frequency and decreasing wavelength) infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays.
