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 clarity, or purity, of a diamond refers to internal inclusions of the diamond, and is one of the 4-Cs in determining a diamond's value.Common inclusions that appear inside diamonds are black carbon spots and small cracks, commonly referred to as fractures or "feathers", due to their feathery whitish appearance when viewed from above or through the side.

The Hoosiers went 11-1 in the regular season and made the College Football Playoff before losing to Notre Dame in the first round on Dec. 21. Rourke was a big reason why. A fringe Heisman ...
Luminescence is caused by the absorption of energy that is released in small amounts. When the energy comes from light or other electromagnetic radiation , it is referred to as photoluminescence ; which is divisible between fluorescence when the glow ceases immediately with the excitation and phosphorescence when the glow continues beyond the ...
